8 Detailed Description

8.1 Overview

The INA180, INA2180, and INA4180 (INAx180) are 26-V, common-mode, current-sensing amplifiers used in

both low-side and high-side configurations. These specially-designed, current-sensing amplifiers accurately

measures voltages developed across current-sensing resistors on common-mode voltages that far exceed the

supply voltage powering the device. Current can be measured on input voltage rails as high as 26 V, and the

devices can be powered from supply voltages as low as 2.7 V.
