INA223 Current Shunt Monitor



Texas Instruments INA223 Current Shunt Monitor

Texas Instruments' analog output current/voltage/power monitor with I²C programmable gain and attenuation


Texas Instruments' 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 common-mode 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.   INA223 Datasheet
