NCS199A1

NCS199A1, NCS199A2, NCS199A3 Current-Shunt Monitor, Voltage Output, Bi-Directional Zero-Drift 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 100 mA of supply current. All versions are specified over the extended operating temperature range (–40°C to +125°C). Features Wide Common−Mode Input Range −0.3 V to 26 V Supply Voltage Range from 2.7 V to 26 V Low Offset Voltage ±150 mV Max Low Offset Drift (0.5 mV/°C) Low Gain Error (max 1.5%) Rail−to−rail Input and Output Capability Low Current Consumption (typ 65 mA, 100 ...
