Current Sense Amplifiers | NCS21671
概览
The NCS21671 and NCV21671 are a series of 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 provided to reduce current drain through the input pins and power supply pins to negligible levels. Two optional pins are included to simplify input filtering. These devices can operate from a single +1.8 V to +5.5 V power supply, drawing a maximum of 40 μA of supply current. These parts are available in Micro10 and SC70-6 packages.
