Description
General part information
INA181 Series
The INA181, INA2181, and INA4181 (INAx181) current sense amplifiers are designed for cost-optimized 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 common-mode 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.
