General Description

The INA225-Q1 is a voltage-output, current-sense amplifier that senses drops across current-sensing resistors at common-mode voltages that vary from 0 V to 36 V, independent of the supply voltage.

The device is a bidirectional, current-shunt monitor that allows an external reference to be used to measure current flowing in both directions across a currentsensing resistor.

Four discrete gain levels are selectable using the two gain-select terminals (GS0 and GS1) to program gains of 25 V/V, 50 V/V, 100 V/V, and 200 V/V.
