The INA21x-Q1 family of devices is a voltage-output, current-shunt monitor (also called a current-sense amplifier) that can sense drops across shunts at common-mode voltages from –0.3 V to 26 V, independent of the supply voltage. Five fixed gains are available: 50 V/V, 75 V/V, 100 V/V, 200 V/V, 500 V/V, and 1000 V/V. This family of devices is commonly used for overcurrent detection, voltage feedback control loops, or as a power monitor. The low offset of the zero-drift architecture enables current sensing with maximum drops across the shunt as low as 10-mV full-scale.
The devices operate from a single 2.7-V to 26-V power supply, drawing a maximum of 100 µA of supply current. The devices are specified over the operating temperature range of –40°C to +125°C and are offered in a 6-pin SC70 package.
