INA240 Bidirectional Current Sensing Amplifier Module, High Accuracy, 3V-5V Wide Supply

High-Accuracy Bidirectional Current Sensing The INA240 current sensing amplifier module delivers high-precision bidirectional current measurement in a compact, easy-to-integrate format. Built around the INA240A2 device, it is designed for engineers, developers and electronics enthusiasts working on battery management, motor control or power systems where accurate current monitoring is essential. Wide Supply Range and Simple Integration Operating from a DC supply of 3V to 5V, the module offers a wide input range that suits a variety of low-voltage applications. Its output is directly proportional to the measured input current, which makes it straightforward to interface with microcontrollers and other digital systems. This linear output behaviour simplifies firmware development and reduces the need for additional signal conditioning. Low Drift for Reliable Measurements The amplifier is engineered for exceptionally low drift, helping to maintain measurement stability across changing operating conditions. This makes it particularly well suited to systems that require consistent, repeatable readings over time, such as closed-loop motor control or battery charge monitoring, where even small inaccuracies can affect overall performance. Practical Applications Whether you are prototyping a power management circuit, building a motor controller or developing a battery monitoring solution, this module provides a dependable way to sense current in both directions. Its straightforward pin layout and wide supply tolerance make it a practical choice for breadboard work, custom PCBs and embedded projects alike.
