3 Description
The INA181, INA2181, and INA4181 (INAx181)
current sense amplifiers are designed for costoptimized
applications. These devices are part of a
family of bidirectional, current-sense amplifiers (also
called current-shunt monitors) that sense voltage
drops across current-sense resistors at commonmode
voltages from –0.2 V to +26 V, independent
of the supply voltage. The INAx181 family integrates
a matched resistor gain network in four, fixed-gain
device options: 20 V/V, 50 V/V, 100 V/V, or 200 V/V.
This matched gain resistor network minimizes gain
error and reduces the temperature drift.
These devices operate from a single 2.7-V to 5.5-
V power supply. The single-channel INA181 draws
a maximum supply current of 260 μA; whereas,
the dual-channel INA2181 draws a maximum supply
current of 500 μA, and the quad-channel INA4181
draws a maximum supply current of 900 μA.
The INA181 is available in both the 6-pin, SOT-23
and SC70 packages. The INA2181 is available in
10-pin, VSSOP and WSON packages. The INA4181
is available in a 20-pin, TSSOP package. All device
options are specified over the extended operating
temperature range of –40°C to +125°C.
