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 is a family of cost-optimized, 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 INA180 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.

The INA180 operates from a single 2.7-V to 5.5-V power supply, drawing a maximum of 260 µA of supply current.

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