The ON Semiconductor voltage output current sense amplifiers offered in gains of 25, 50, 100, and 200 V/V. These parts can measure voltage across shunts at common mode voltages from −0.1 V to 40 V, independent of supply voltage. The low offset of the zero drift architecture enables current sensing with voltage drops across sense resistors as low as 10 mV full scale. An optional enable function is available to reduce current drain through the input pins and power supply pins to negligible levels when disabled. Two optional pins are included to simplify input filtering.
