7Semi INA240A4 480V Bidirectional Current Sensor Breakout Board

The 7Semi INA240A4 480V Bidirectional Current Sensor Breakout Board is designed for accurate current measurement in applications where current can flow in either direction. Based on the INA240A4 current-sense amplifier, it supports a wide bus-voltage range of 4 V to +80 V and can measure currents up to 2.5 A, making it useful for a variety of power and embedded electronics projects.

Its 200 V/V gain helps provide clear current-sensing signals, while enhanced PWM rejection improves measurement stability in systems using PWM signals, such as motor drivers and switching power circuits. This bidirectional current sensor is well suited for motor control, battery monitoring, power supply monitoring, power management, and embedded current measurement applications. Its breakout-board format also makes it convenient for prototyping and integrating current sensing into custom electronic systems.
