General Description

The INA223 is a voltage-output device that monitors the current, bus voltage, and power of a supply line by sensing a voltage drop across a shunt at commonmode voltages from 0 V to 26 V.

The common-mode voltage range is independent of the supply voltage.

The low offset of the Zerø-Drift architecture enables current sensing with maximum drops across the shunt as low as 10 mV, full-scale.
