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.
