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.
