INA240 Overview
The INA240 device is a voltage-output, current-sense amplifier with enhanced PWM rejection that can sense drops across shunt resistors over a wide mon-mode voltage range from 4 V to 80 V, independent of the supply voltage. The negative mon-mode voltage allows the device to operate below ground, acmodating the flyback period of typical solenoid applications. Enhanced PWM rejection provides high levels of suppression...
