General Description
The MAX4475–MAX4478/MAX4488/MAX4489 wide-
band, low-noise, low-distortion operational amplifiers
offer rail-to-rail outputs and single-supply operation
down to 2.7V. They draw 2.2mA of quiescent supply
current per amplifier while featuring ultra-low distortion
(0.0002% THD+N), as well as low input voltage-noise
density (4.5nV/√Hz) and low input current-noise density
(0.5fA/√Hz). These features make the devices an ideal
choice for applications that require low distortion and/or
low noise.
For power conservation, the MAX4475/MAX4488 offer a
low-power shutdown mode that reduces supply current
to 0.01µA and places the amplifiers’ outputs into a high-
impedance state. These amplifiers have outputs which
swing rail-to-rail and their input common-mode voltage
range includes ground. The MAX4475–MAX4478 are
unity-gain stable with a gain-bandwidth product of
10MHz. The MAX4488/4489 are internally compensated
for gains of +5V/V or greater with a gain-bandwidth
product of 42MHz. The single MAX4475/MAX4476/
MAX4488 are available in space-saving, 6-pin SOT23
and TDFN packages.

Detailed Description
The MAX4475–MAX4478/MAX4488/MAX4489 single-
supply operational amplifiers feature ultra-low noise
and distortion. Their low distortion and low noise make
them ideal for use as preamplifiers in wide dynamic-
range applications, such as 16-bit analog-to-digital
converters (see Typical Operating Circuit). Their high-
input impedance and low noise are also useful for sig-
nal conditioning of high-impedance sources, such as
piezoelectric transducers.
These devices have true rail-to-rail ouput operation,
drive loads as low as 1kΩwhile maintining DC accura-
cy, and can drive capactive loads up to 200pF without
oscillation. The input common-mode voltage range
extends from (VDD - 1.6V) to 200mV below the negative
rail. The push-pull output stage maintains excellent DC
characteristics, while delivering up to ±5mA of current.
The MAX4475–MAX4478 are unity-gain stable, while
the MAX4488/MAX4489 have a higher slew rate and
are stable for gains ≥5V/V. The MAX4475/MAX4488
feature a low-power shutdown mode, which reduces
the supply current to 0.01µA and disables the outputs.
Low Distortion
Many factors can affect the noise and distortion that the
device contributes to the input signal. The following
guidelines offer valuable information on the impact of
design choices on Total Harmonic Distortion (THD).
Choosing proper feedback and gain resistor values for
a particular application can be a very important factor
in reducing THD. In general, the smaller the closed-
loop gain, the smaller the THD generated, especially
when driving heavy resistive loads. The THD of the part
normally increases at approximately 20dB per decade,
as a function of frequency. Operating the device near
or above the full-power bandwidth significantly
degrades distortion.
Referencing the load to either supply also improves the
part’s distortion performance, because only one of the
MOSFETs of the push-pull output stage drives the out-
put. Referencing the load to midsupply increases the
part’s distortion for a given load and feedback setting.
(See the Total Harmonic Distortion vs. Frequency graph
in the Typical Operating Characteristics.)
For gains ≥5V/V, the decompensated devices
MAX4488/MAX4489 deliver the best distortion perfor-
mance, since they have a higher slew rate and provide
a higher amount of loop gain for a given closed-loop
gain setting. Capacitive loads below 100pF do not sig-
nificantly affect distortion results. Distortion perfor-
mance is relatively constant over supply voltages.

Low Noise
The amplifier’s input-referred noise-voltage density is
dominated by flicker noise at lower frequencies, and by
thermal noise at higher frequencies. Because the ther-
mal noise contribution is affected by the parallel combi-
nation of the feedback resistive network (RF|| RG,
Figure 1), these resistors should be reduced in cases
where the system bandwidth is large and thermal noise
is dominant. This noise contribution factor decreases,
however, with increasing gain settings.
For example, the input noise-voltage density of the cir-
cuit with RF= 100kΩ, RG= 11kΩ(AV= +5V/V) is
en= 14nV/√Hz, encan be reduced to 6nV/√Hz by
choosing RF= 10kΩ, RG= 1.1kΩ(AV= +5V/V), at the
expense of greater current consumption and potentially
higher distortion. For a gain of 100V/V with RF= 100kΩ,
RG= 1.1kΩ, the enis still a low 6nV/√Hz.
Using a Feed-Forward Compensation
Capacitor, CZ
The amplifier’s input capacitance is 10pF. If the resis-
tance seen by the inverting input is large (feedback
network), this can introduce a pole within the amplifier’s
bandwidth resulting in reduced phase margin.
Compensate the reduced phase margin by introducing
a feed-forward capacitor (CZ) between the inverting
input and the output (Figure 1). This effectively cancels
the pole from the inverting input of the amplifier.
Choose the value of CZas follows:
CZ= 10 x (RF/ RG) [pF]
In the unity-gain stable MAX4475–MAX4478, the use of
a proper CZis most important for AV= +2V/V, and
AV = -1V/V. In the decompensated MAX4488/
MAX4489, CZis most important for AV= +10V/V.
Figures 2a and 2b show transient response both with
and without CZ.
Using a slightly smaller CZthan suggested by the for-
mula above achieves a higher bandwidth at the
expense of reduced phase and gain margin. As a gen-
eral guideline, consider using CZfor cases where RG||
RFis greater than 20kΩ(MAX4475–MAX4478) or
greater than 5kΩ(MAX4488/MAX4489).
Applications Information
The MAX4475–MAX4478/MAX4488/MAX4489 combine
good driving capability with ground-sensing input and
rail-to-rail output operation. With their low distortion and
low noise, they are ideal for use in ADC buffers, med-
ical instrumentation systems and other noise-sensitive
applications.
Ground-Sensing and Rail-to-Rail Outputs
The common-mode input range of these devices
extends below ground, and offers excellent common-
mode rejection. These devices are guaranteed not to
undergo phase reversal when the input is overdriven
(Figure 3).
Figure 4 showcases the true rail-to-rail output operation
of the amplifier, configured with AV= 5V/V. The output
swings to within 8mV of the supplies with a 10kΩload,
making the devices ideal in low-supply voltage applica-
tions.
Power Supplies and Layout
The MAX4475–MAX4478/MAX4488/MAX4489 operate
from a single +2.7V to +5.5V power supply or from dual
supplies of ±1.35V to ±2.75V. For single-supply opera-
tion, bypass the power supply with a 0.1µF ceramic

capacitor placed close to the VDD pin. If operating from
dual supplies, bypass each supply to ground.
Good layout improves performance by decreasing the
amount of stray capacitance and noise at the op amp’s
inputs and output. To decrease stray capacitance, min-
imize PC board trace lengths and resistor leads, and
place external components close to the op amp’s pins.
Typical Application Circuit
The Typical Application Circuit shows the single
MAX4475 configured as an output buffer for the
MAX5541 16-bit DAC. Because the MAX5541 has an
unbuffered voltage output, the input bias current of the
op amp used must be less than 6nA to maintain 16-bit
accuracy. The MAX4475 has an input bias current of
only 150pA (max), virtually eliminating this as a source
of error. In addition, the MAX4475 has excellent open-
loop gain and common-mode rejection, making this an
excellent ouput buffer amplifier.
DC-Accurate Lowpass Filter
The MAX4475–MAX4478/MAX4488/MAX4489 offer a
unique combination of low noise, wide bandwidth, and
high gain, making them an excellent choice for active
filters up to 1MHz. The Typical Operating Circuit shows
the dual MAX4477 configured as a 5th order
Chebyschev filter with a cutoff frequency of 100kHz.
The circuit is implemented in the Sallen-Key topology,
making this a DC-accurate filter.
