The INA240A1 is a precision current-sense amplifier designed to measure electrical current accurately, especially in electrically noisy systems such as motors, solenoids, power converters, and industrial actuators. It delivers clean and reliable current feedback where conventional current-sense amplifiers may struggle with PWM noise
Key Features
- Measures the small voltage developed across the onboard 10 mΩ 3W shunt resistor with minimal impact on the load voltage.
- Supports bidirectional current measurement, enabling accurate monitoring of current flowing in either direction.
- Features an adjustable zero-current output level through the REF1 and REF2 inputs.
- Supports flexible high-side, low-side and inline current-sensing configurations.
- Ideal for motor drives, solenoids, actuators, power supplies, robotics and industrial control systems.
