The 7Semi INA240A2 Current Sense Module provides accurate bidirectional current measurement for motor drives, solenoids, actuators, power supplies, and industrial control systems. Its fixed 50V/V gain offers high sensitivity, while enhanced PWM rejection delivers a clean and stable analog output in electrically noisy switching environments. The module measures the small voltage developed across its onboard 10mΩ shunt resistor with minimal impact on the load voltage. REF1 and REF2 inputs allow adjustment of the zero-current output level for unidirectional or bidirectional operation.
Key Features
- Fixed 50V/V gain for sensitive and accurate current measurement.
