INA191 General Description

The INAx191 is a low-power, voltage-output, current-shunt monitor (also called a current-sense amplifier) that is commonly used for overcurrent protection, precision-current measurement for system optimization, or in closed-loop feedback circuits. This device can sense drops across shunts at common.
