Amplifiers

Current SenseAutomotiveAEC-Q100PWM Rejection

The INA240A3QDRQ1 is an automotive-grade, high-precision current sense amplifier with a fixed gain of 100V/V, designed for harsh environments with high PWM switching noise.

Best for

  • Automotive motor control
  • Solenoid and valve control
  • High-transient PWM environments

Avoid if

  • Applications requiring very low supply voltages below 2.7V
  • Non-automotive cost-sensitive designs where standard amplifiers suffice

Check before use

  • Ensure the shunt resistor power dissipation is within limits.
  • Verify the common-mode voltage does not exceed 80V.
