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.
