INA240 Datasheet (Texas Instruments) - Ultra-Precise Current Sense Amplifier

INA240, Ultra-Precise Current Sense Amplifier

The INA240 device is a voltage-output, current-sense amplifier with enhanced PWM rejection that can sense drops across shunt resistors over a wide common-mode voltage range from *4 V to 80 V, independent of the supply voltage.

The negative common-mode voltage allows the device to operate be
