INA186 Overview
The INA186 is a low-power, voltage-output, currentsense amplifier (also called a current-shunt monitor). This device is monly used for overcurrent protection, precision current measurement for system optimization, or in closed-loop feedback circuits. The INA186 can sense drops across shunts at monmode voltages from 0.2 V to +40 V, independent of the supply voltage.
