The NCS199A1R is a voltage output current shunt monitor (also called current sense amplifier) which can measure voltage across shunts at common-mode voltages from -0.3 to 26V, independent of supply voltage. The low offset of the zero-drift architecture enables current sensing across the shunt with maximum voltage drop as low as 10 mV full-scale.
