Official 7Semi INA240A2 4~80V Bidirectional Current Sense Amplifier Breakout, 50V/V Gain

The 7Semi INA240 Breakout Board is a precision-engineered current sensing solution built around the Texas Instruments INA240, a high-performance current-sense amplifier designed specifically for noisy, high-voltage environments. With a fixed gain of 50 V/V and support for bidirectional current measurement, this module enables accurate monitoring of current flow in demanding applications such as motor drives, power inverters, robotics, and industrial power management systems.

One of the standout features of the INA240 is its wide common-mode voltage range of –4V to 80V, allowing safe and reliable current sensing on high-side or low-side shunt resistors—even in systems with large voltage swings. Unlike conventional current-sense amplifiers, the INA240 incorporates Enhanced PWM Rejection (PWM-R) technology, which dramatically reduces measurement errors caused by fast switching edges in PWM-controlled systems. This ensures stable and accurate current readings even in environments with high dv/dt and electrical noise.

The 7Semi breakout design simplifies integration into embedded systems by providing easy access to all critical pins, making it ideal for rapid prototyping and production designs alike. The analog output voltage is directly proportional to the sensed current, allowing seamless interfacing with microcontrollers, ADCs, DSPs, and control units. Its compact footprint and robust performance make it a preferred choice for motor current monitoring, power supply diagnostics, battery management systems, and automotive electronics.

Whether you are an engineer designing industrial motor controllers or a developer working on advanced robotics or energy systems, the 7Semi INA240 Breakout Board delivers reliable, high-accuracy current sensing where precision truly matters.
