26V, Low- or High-Side Voltage Output Current Sense Amplifier - INA180

INA180 (ACTIVE)

26V, Low- or High-Side Voltage Output Current Sense Amplifier

 

Description

The INA180 and INA2180 (INAx180) current sense amplifiers are designed for cost-optimized applications. These devices are part of a family of 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 INAx180 integrate 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.

Both the INA180 and INA2180 operate from a single 2.7-V to 5.5-V power supply. The single-channel INA180 draws a maximum supply current of 260 µA; whereas, the dual-channel INA2180 draws a maximum supply current of 520 µA..

The INA180 is available in a 5-pin, SOT-23 package with two different pin configurations. The INA2180 is available in an 8-pin VSSOP package. All device options are specified over the extended operating temperature range of –40°C to +125°C.
