Three fixed gains are available: 50V/V, 100V/V, and 200V/V. The low offset of the zero-drift architecture enables current sensing with maximum drops across the shunt as low as 10-mV full-scale. This device operates from a single 2.7-V to 26-V power supply, drawing a maximum of 100 μA of supply current. All gain options are specified from –40°C to +125°C, and are offered i...
