General Description
The MAX4460/MAX4461/MAX4462 are instrumentation
amplifiers with precision specifications, low-power con-
sumption, and excellent gain-bandwidth product.
Proprietary design techniques allow ground-sensing
capability combined with ultra-low input current and
increased common-mode rejection performance. These
rail-to-rail output instrumentation amplifiers are offered in
fixed or adjustable gains and the option for either a shut-
down mode or a pin to set the output voltage relative to
an external reference (see the Ordering Information and
Selector Guide).
The MAX4460 has an adjustable gain and uses ground
as its reference voltage. The MAX4461 is offered in fixed
gains of 1, 10, and 100, uses ground as its reference volt-
age, and has a logic-controlled shutdown input. The
MAX4462 is offered in fixed gains of 1, 10, and 100 and
has a reference input pin (REF). REF sets the output volt-
age for zero differential input to allow bipolar signals in
single-supply applications.
The MAX4460/MAX4461/MAX4462 have high-impedance
inputs optimized for small-signal differential voltages. The
MAX4461/MAX4462 are factory trimmed to gains of 1, 10,
or 100 (suffixed U, T, and H) with ±0.1% accuracy. The
typical offset of the MAX4460/MAX4461/MAX4462 is
100µV. All devices have a gain-bandwidth product of
2.5MHz.
These amplifiers operate with a single-supply voltage
from 2.85V to 5.25V and with a quiescent current of only
700µA (less than 1µA in shutdown for the MAX4461). The
MAX4462 can also be operated with dual supplies.
Smaller than most competitors, the MAX4460/
MAX4461/MAX4462 are available in space-saving 6-pin
SOT23 and TDFN packages.

Note 1: Offset Voltage is measured with a best straight-line (BSL) method (see A User Guide to Instrumentation Amplifier Accuracy
Specifications section).
Note 2: IN+ and IN- are gates to CMOS transistors with typical input bias current of 1pA. CMOS leakage is so small that it is
impractical to test and guarantee in production. Limits shown are guaranteed by design. However, devices are functionally
screened during production testing to eliminate defective units.
Note 3: Output swing high is measured only on G = 100 devices. Devices with G = 1 and G = 10 have output swing high limited by
the range of VREF, VCM, and VDIFF (see Output Swing section).
Note 4: Short-circuit duration limited to 1s (see Absolute Maximum Ratings).
Note 5: SOT23 and TDFN units are 100% production tested at +25°C. Limits over temperature are guaranteed by design.

Detailed Description
The MAX4460/MAX4461/MAX4462 family of instrumen-
tation amplifiers implements Maxim’s proprietary indi-
rect current-feedback design to achieve a precision
specification and excellent gain-bandwidth product.
These new techniques allow ground-sensing capability
combined with an ultra-low input current and an
increased common-mode rejection.
The differential input signal is converted to a current by
an input transconductance stage. An output transcon-
ductance stage converts a portion of the output voltage
(equal to the output voltage divided by the gain) into
another precision current. These two currents are sub-
tracted and the result is fed to a loop amplifier with a
class AB output stage with sufficient gain to minimize
errors (Figure 1).
The MAX4461U/T/H and MAX4462U/T/H have factory-
trimmed gains of 1, 10, and 100, respectively. The
MAX4460 has an adjustable gain, set with an external
pair of resistors between pins OUT, FB, and GND
(Figure 2).
The MAX4462U/T/H has a reference input (REF) which
is connected to an external reference for bipolar opera-
tion of the device. The range for VREF is 0.1V to (VDD -
1.7V). For full output-swing capability, optimal perfor-
mance is usually obtained with VREF = VDD/2.
The MAX4460/MAX4461/MAX4462 operate with single-
supply voltages of 2.85V to 5.25V. It is possible to use the
MAX4462U/T/H in a dual-supply configuration with up to
±2.6V at VDD and VSS, with REF connected to ground.
The MAX4461U/T/H has a shutdown feature to reduce
the supply current to less than 1µA. The MAX4461U/
T/H output is internally referenced to ground, making
the part suitable for unipolar operations.
The MAX4460 has an FB pin that can be used to exter-
nally set the gain through a pair of resistors (see Setting
the Gain (MAX4460) section). The MAX4460 output is
internally referenced to ground, making the part suitable
for unipolar operations.

Input Common-Mode and Output
Reference Ranges
MAX4460/MAX4461/MAX4462 have an input common-
mode range of 100mV below the negative supply to
1.7V below the positive supply.
The output reference voltage of MAX4462U/T/H is set by
REF and ranges from 100mV above the negative supply
to 1.7V below the positive supply. For maximum voltage
swing in a bipolar operation, connect REF to VDD/2.
The output voltages of the MAX4460 and MAX4461U/
T/H are referenced to ground. Unlike the traditional
three-op-amp configuration of common instrumentation
amplifiers, the MAX4460/MAX4461/MAX4462 have
ground-sensing capability (or to VSS in dual-supply
configuration) in addition to the extremely high input
impedances of MOS input differential pairs.
Input Differential Signal Range
The MAX4460/MAX4461/MAX4462 feature a proprietary
input structure optimized for small differential signals.
The unipolar output of the MAX4460/MAX4461 is nomi-
nally zero-for-zero differential input. However, these
devices are specified for inputs of 50mV to 100mV for
the unity-gain devices, 20mV to 100mV for gain of 10
devices, and 2mV to 48mV for gain of 100 devices. The
MAX4460/MAX4461 can be used with differential inputs
approaching zero, albeit with reduced accuracy.
The bipolar output of the MAX4462 allows bipolar input
ranges. The output voltage is equal to the reference
voltage for zero differential input. The MAX4462 is
specified for inputs of ±100mV for the unity gain and
gain of 10 devices, and ±20mV for gain of 100 devices.
The gain of 100 devices (MAX4462H) can be operated
beyond 20mV signal provided the reference is chosen
for unsymmetrical swing.
Output Swing
The MAX4460/MAX4461/MAX4462 are designed to
have rail-to-rail output voltage swings. However,
depending on the selected gain and supply voltage
(and output reference level of the MAX4462), the rail-to-
rail output swing is not required.
For example, consider the MAX4461U, a unity-gain
device with its ground pin as the output reference level.
The input voltage range is 0 to 100mV (50mV minimum
to meet accuracy specifications). Because the device
is unity gain and the output reference level is ground,
the output only sees excursions from ground to 100mV.
Devices with higher gain and with bipolar output such
as the MAX4462, can be configured to swing to higher
levels. In these cases, as the output approaches either
supply, accuracy may degrade, especially under heavy
output loading.
Shutdown Mode
The MAX4461U/T/H features a low-power shutdown
mode. When the SHDN pin is pulled low, the internal
transconductance and amplifier blocks are switched off
and supply current drops to typically less than 0.1µA
(Figure 1).
In shutdown, the amplifier output is high impedance.
The output transistors are turned off, but the feedback
resistor network remains connected. If the external load
is referenced to GND, the output drops to approximate-
ly GND in shutdown. The output impedance in shut-
down is typically greater than 100kΩ. Drive SHDN high
or connect to VCC for normal operation.
A User Guide to Instrumentation
Amplifier Accuracy Specifications
As with any other electronic component, a complete
understanding of instrumentation amplifier specifica-
tions is essential to successfully employ these devices
in their application circuits. Most of the specifications
for these differential closed-loop gain blocks are similar
to the well-known specifications of operational ampli-
fiers. However, there are a few accuracy specifications
that could be confusing to first-time users. Therefore,
some explanations and examples may be helpful.
Accuracy specifications are measurements of close-
ness of an actual output response to its ideal
expected value. There are three main specifications
in this category:
●Gain error
●Gain nonlinearity error
●Offset error
In order to understand these terms, we must look at the
transfer function of an ideal instrumentation amplifier. As
expected, this must be a straight line passing through
origin with a slope equal to the ideal gain (Figure 3). If
the ideal gain is equal to 10 and the extreme applied
input voltages are -100mV and +100mV, then the value
of the output voltages are -1V and +1V, respectively.
Note that the line passes through the origin and therefore
a zero input voltage gives a zero output response.
The transfer function of a real instrumentation amplifier
is quite different from the ideal line pictured in Figure 3.
Rather, it is a curve such as the one indicated as the
typical curve in Figure 4, connecting end points A and B.

14 ______________________________________________________________________________________
Looking at this curve, one can immediately identify
three types of errors.
First, there is an obvious nonlinearity (curvature) when
this transfer function is compared to a straight line.
More deviation is measured as greater nonlinearity
error. This is explained in more detail below.
Second, even if there was no nonlinearity error, i.e., the
actual curve in Figure 4 was a straight line connecting
end points A and B, there exists an obvious slope devi-
ation from that of an ideal gain slope (drawn as the
“ideal” line in Figure 4). This rotational error (delta
slope) is a measure of how different the actual gain
(GA) is from the expected ideal gain (GI) and is called
gain error (GE) (see the equation below).
Third, even if the actual curve between points A and B
was a straight line (no nonlinearity error) and had the
same slope as the ideal gain line (no gain error), there
is still another error called the end-point offset error (OE
on vertical axis), since the line is not passing through
the origin.
Figure 5 is the same as Figure 4, but the ideal line (CD)
is shifted up to pass through point E (the Y intercept of
end-points line AB).
This is done to better visualize the rotational error (GE),
which is the difference between the slopes of end
points line AB and the shifted ideal line CD.

______________________________________________________________________________________ 15
The rotational nature of gain error, and the fact that it is
pivoted around point E in Figure 5, shows that gain-
error contribution to the total output voltage error is
directly proportional to the input voltage. At zero input
voltage, the error contribution of gain error is zero, i.e.,
the total deviation from the origin (the expected zero
output value) is only due to end-points OE and nonlin-
earity error at zero value of input (segment EZ on the
vertical axis).
The nonlinearity is the maximum deviation from a
straight line, and the end-point nonlinearity is the devia-
tion from the end-point line. As shown in Figure 5, it is
likely that two nonlinearities are encountered, one posi-
tive and the other a negative nonlinearity error, shown
as NL+ and NL- in Figure 5.
Generally, NL+ and NL- have different values and this
remains the case if the device is calibrated (trimmed)
for end-points errors (which means changing the gain
of the instrumentation amplifier in such a way that the
slope of line AB becomes equal to that of CD, and the
offset becomes trimmed such that OE vanishes to
zero). This is an undesirable situation when nonlinearity
is of prime interest.
The straight line shown in Figure 6 is in parallel to end-
points line AB and has a Y intercept of OS on the verti-
cal axis. This line is a shifted end-points line such that
the positive and negative nonlinearity errors with
respect to this line are equal. For this reason, the line is
called the best straight line (BSL). Maxim internally
trims the MAX4460/MAX4461/MAX4462 with respect to
this line (changing the gain slope to be as close as
possible to the slope of the ideal line and trimming the
offset such that OS gets as close to the origin as possi-
ble) to minimize all the errors. The total accuracy error
is still the summation of the gain error, nonlinearity, and
offset errors.
As an example, assume the following specification for
an instrumentation amplifier:
Gain = 10
GE = 0.15%
Offset (BSL) = 250µV
NL = 0.05%
VDIF (input) = -100mV to +100mV
What is the maximum total error associated with the
GE, offset (BSL), and NL? With a differential input range
of -0.1V to +0.1V and a gain of 10, the output voltage
assumes a range of -1V to +1V, i.e., a total full-scale
range of 2V.
The individual errors are as follows:
GE = (0.15%) (10) (100mV) = 1.5mV
Offset (BSL) = (250µV) (10) = 2.5mV
NL = (0.05%) (2V) = 1mV
Maximum Total Error = 1.5mV + 2.5mV + 1mV
= 5mV
So, the absolute value of the output voltage, consider-
ing the above errors, would be at worst case between
0.995V to 1.005V. Note that other important parameters
such as PSRR, CMRR, and noise also contribute to the
total error in instrumentation applications. They are not
considered here.

Applications Information
Setting the Gain (MAX4460)
The MAX4460 gain is set by connecting a resistive-
divider from OUT to GND, with the center tap connect-
ed to FB (Figure 2). The gain is calculated by:
Gain = 1 + R2 / R1
Because FB has less than 100pA IB, high-valued resis-
tors can be used without significantly affecting the gain
accuracy. The sum of resistors (R1 + R2) near 100kΩis
a good compromise. Resistor accuracy directly affects
gain accuracy. Resistor sum less than 20kΩshould not
be used because their loading can slightly affect output
accuracy.
Capacitive-Load Stability
The MAX4460/MAX4461/MAX4462 are capable of dri-
ving capacitive loads up to 100pF.
Applications needing higher capacitive drive capability
may use an isolation resistor between OUT and the
load to reduce ringing on the output signal. However
this reduces the gain accuracy due to the voltage drop
across the isolation resistor.
Output Loading
For best performance, the output loading should be to
the potential seen at REF for the MAX4462 or to ground
for the MAX4460/MAX4461.
REF Input (MAX4462)
The REF input of the MAX4462 can be connected to any
voltage from (VSS + 0.1V) to (VDD - 1.7V). A buffered
voltage-divider with sink and source capability works
well to center the output swing at VDD/2. Unbuffered
resistive dividers should be avoided because the 100kΩ
(typ) input impedance of REF causes amplitude-depen-
dent variations in the divider’s output.
Bandgap references, either series or shunt, can be
used to drive REF. This provides a voltage and temper-
ature invariant reference. This same reference voltage
can be used to bias bridge sensors to eliminate supply
voltage ratiometricity. For proper operation, the refer-
ence must be able to sink and source at least 25µA.
In many applications, the MAX4462 is connected to a
CODEC or other device with a reference voltage out-
put. In this case, the receiving device’s reference out-
put makes an ideal reference voltage. Verify the
reference output of the device is capable of driving the
MAX4462’s REF input.
Power-Supply Bypass and Layout
Good layout technique optimizes performance by
decreasing the amount of stray capacitance at the
instrumentation amplifier’s gain-setting pins. Excess
capacitance produces peaking in the amplifier’s fre-
quency response. To decrease stray capacitance, min-
imize trace lengths by placing external components as
close to the instrumentation amplifier as possible. For
best performance, bypass each power supply to
ground with a separate 0.1µF capacitor.
Microphone Amplifier
The MAX4462’s bipolar output, along with its excellent
common-mode rejection ratio, makes it suitable for pre-
cision microphone amplifier applications. Figure 7 illus-
trates one such circuit. In this case, the electret
microphone is resistively biased to the supply voltage
through a 2.2kΩpullup resistor. The MAX4462 directly
senses the output voltage at its noninverting input, and
indirectly senses the microphone’s ground through an
AC-coupling capacitor. This technique provides excel-
lent rejection of common-mode noise picked up by the
microphone lead wires. Furthermore, ground noise from
distantly located microphones is reduced.
The single-ended output of the MAX4462 is converted to
differential through a single op amp, the MAX4335. The
op amp forces the midpoint between OUT+ and OUT- to
be equal to the reference voltage. The configuration
does not change the MAX4662T’s fixed gain of 10.
