1 Device Information

The INA240-SEP 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 below ground, accommodating the flyback period of typical solenoid applications. This device operates from a single 2.7-V to 5.5-V power supply, drawing a maximum of 2.4 mA of supply current. The fixed gain is 20 V/V. The low offset of the zero-drift architecture enables current sensing with maximum drops across the shunt as low as 10-mV full-scale.
