INA240 Current Detection Amplifier Current Voltage Monitoring Bidirectional Module

The INA240 current detection module is a precision current-sensing amplifier, ideal for high-side or low-side current measurement in motor drives, power management systems, and solenoid control. With a wide common-mode voltage range from -4V to 80V, it enables accurate differential sensing across shunt resistors even in complex environments. The enhanced PWM rejection technology ensures minimal output ripple and high measurement integrity in fast-switching systems. Operating at 3V to 5V, with a fixed gain of 200V/V, this module offers a compact and reliable solution for embedded applications where stability, speed, and efficiency matter. Features Wide -4V to 80V common-mode input voltage range Enhanced PWM suppression for accurate current sensing High CMRR: 132dB DC / 93dB AC at 50kHz Works with 3.0V–5.0V supply voltage Fixed gain: 200V/V (INA240A4 variant) Suitable for both high-side and low-side sensing Package Includes 1 x INA240 current detection module proxy 1 x Header Pin Related
