Current-Shunt Monitors, 40V Common Mode, Unidirectional, Single, Dual

   The NCS21673 and NCS21674 are a series of current sense amplifiers offered in gains of 20, 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. This helps measuring of fast transients and allows the same type of part to be used for high side and low side current sensing. These devices can operate from a single 2.7 V to 5.5 V power supply.
