7 Detailed Description

7.1 Overview

The INA190-Q1 is a low bias current, low offset, 40-V common-mode, current-sensing amplifier. The INA190-Q1

is a specially designed, current-sensing amplifier that accurately measures voltages developed across current-

sensing resistors on common-mode voltages that far exceed the supply voltage. Current is measured on input

voltage rails as high as 40 V at VIN+ and VIN–, with a supply voltage, VS, as low as 1.7 V. The INA190-Q1 is

intended for use in both low-side and high-side current-sensing configurations where high accuracy and low

current consumption are required.
