CURRENT SHUNT MONITOR
DESCRIPTION
The INA138 and INA168 are high-side, unipolar, current
shunt monitors. Wide input common-mode voltage range,
low quiescent current, and tiny SOT23 packaging enable use
in a variety of applications.
Input common-mode and power-supply voltages are inde-
pendent and can range from 2.7V to 36V for the INA138 and
2.7V to 60V for the INA168. Quiescent current is only 25µA,
which permits connecting the power supply to either side of
the current measurement shunt with minimal error.
The device converts a differential input voltage to a current
output. This current is converted back to a voltage with an
external load resistor that sets any gain from 1 to over 100.
Although designed for current shunt measurement, the circuit
invites creative applications in measurement and level shifting.
Both the INA138 and INA168 are available in SOT23-5 and
are specified for the –40°C to +125°C temperature range.

DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru-
ments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.

OPERATION
Figure 1 illustrates the basic circuit diagram for both the
INA138 and INA168. Load current IS is drawn from supply VS
through shunt resistor RS. The voltage drop in shunt resistor
VS is forced across RG1 by the internal op amp, causing
current to flow into the collector of Q1. External resistor RL
converts the output current to a voltage, VOUT, at the OUT pin.
The transfer function for the INA138 is:
IO = gm (VIN+ – VIN– )(1)
where gm = 200µA/V.
In the circuit of Figure 1, the input voltage, (VIN+ – VIN– ), is
equal to IS • RS and the output voltage, VOUT, is equal to
IO • R
L. The transconductance, gm, of the INA138 is
200µA/V. The complete transfer function for the current
measurement amplifier in this application is:
VOUT = (IS) (RS) (200µA/V) (RL)(2)
The maximum differential input voltage for accurate mea-
surements is 0.5V, which produces a 100µA output current.
A differential input voltage of up to 2V will not cause damage.
Differential measurements (pins 3 and 4) must be unipolar
with a more-positive voltage applied to pin 3. If a more-
negative voltage is applied to pin 3, the output current, IO, will
be zero, but it will not cause damage.
BASIC CONNECTION
Figure 1 shows the basic connection of the INA138. The
input pins, VIN+ and VIN– , should be connected as closely as
possible to the shunt resistor to minimize any resistance in
series with the shunt resistance. The output resistor, RL, is
shown connected between pin 1 and ground. Best accuracy
is achieved with the output voltage measured directly across
RL. This is especially important in high-current systems
where load current could flow in the ground connections,
affecting the measurement accuracy.
No power-supply bypass capacitors are required for stability
of the INA138. However, applications with noisy or high-
impedance power supplies may require decoupling capaci-
tors to reject power-supply noise. Connect bypass capacitors
close to the device pins.
POWER SUPPLIES
The input circuitry of the INA138 can accurately measure
beyond its power-supply voltage, V+. For example, the V+
power supply can be 5V, whereas the load power supply
voltage is up to +36V (or +60V with the INA168). The output
voltage range of the OUT terminal, however, is limited by the
lesser of the two voltages (see “Output Voltage Range” section).
SELECTING RS AND RL
The value chosen for the shunt resistor, RS, depends on the
application and is a compromise between small-signal accu-
racy and maximum permissible voltage loss in the measure-
ment line. High values of RS provide better accuracy at lower
currents by minimizing the effects of offset, while low values of
RS minimize voltage loss in the supply line. For most applica-
tions, best performance is attained with an RS value that
provides a full-scale shunt voltage range of 50mV to 100mV.
Maximum input voltage for accurate measurements is 500mV.
RL is chosen to provide the desired full-scale output voltage.
The output impedance of the INA138 OUT terminal is very
high which permits using values of RL up to 500kΩ with
excellent accuracy. The input impedance of any additional
circuitry at the output should be much higher than the value
of RL to avoid degrading accuracy.

Some Analog-to-Digital (A/D) converters have input imped-
ances that will significantly affect measurement gain. The input
impedance of the A/D converter can be included as part of the
effective RL if its input can be modeled as a resistor to ground.
Alternatively, an op amp can be used to buffer the A/D converter
input. Figure 1 shows the recommended values of RL.
OUTPUT VOLTAGE RANGE
The output of the INA138 is a current, which is converted to
a voltage by the load resistor, RL. The output current remains
accurate within the compliance voltage range of the output
circuitry. The shunt voltage and the input common-mode and
power-supply voltages limit the maximum possible output
swing. The maximum output voltage compliance is limited by
the lower of the two equations below:
Vout max = (V+) – 0.7V – (VIN+ – VIN–)(3)
or
Vout max = VIN– – 0.5V (4)
(whichever is lower)
BANDWIDTH
Measurement bandwidth is affected by the value of the load
resistor, RL. High gain produced by high values of RL will
yield a narrower measurement bandwidth (see Typical
Characteristics). For widest possible bandwidth, keep the
capacitive load on the output to a minimum. Reduction in
bandwidth due to capacitive load is shown in the Typical
Characteristics.
If bandwidth limiting (filtering) is desired, a capacitor can be
added to the output (see Figure 3). This will not cause
instability.
APPLICATIONS
The INA138 is designed for current shunt measurement
circuits, as shown in Figure 1, but its basic function is useful
in a wide range of circuitry. A creative engineer will find many
unforeseen uses in measurement and level shifting circuits.
A few ideas are illustrated in Figures 2 through 7.
