The NCS199A1, NCS199A2 and NCS199A3 are voltage output current shunt monitors that can measure voltage across shunts at common−mode voltages from −0.3 V to 26 V, independent of supply voltage. Three fixed gains are available: 50 V/V, 100 V/V or 200 V/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. The devices can operate from a single +2.7 V to +26 V power supply, drawing a maximum of 100µA of supply current. All versions are specified over the extended operating temperature range (–40°C to +125°C).
