Amplifiers

Current SenseZero-DriftPWM RejectionBidirectional

The INA240A1PWR is a high-precision, zero-drift current-sense amplifier optimized for PWM-heavy applications like motor and solenoid control.

Best for

  • Inline motor current sensing
  • Solenoid and valve control
  • PWM-based power systems

Avoid if

  • Applications requiring extremely low power consumption below 2.4mA
  • Systems where common-mode voltage exceeds 80V

Check before use

  • Ensure the common-mode voltage stays within the -4V to 80V range.
  • Verify the gain (20V/V) is appropriate for your shunt resistor and ADC input range.
