Component

current-sense amplifierbidirectional20 V/V gainAEC-Q100PWM rejectionSOIC-8

INA241A2QDRQ1 is a 20 V/V automotive current-sense amplifier designed for accurate bidirectional measurements in switching systems with high common-mode voltage.

Best for

  • Automotive motor current sensing
  • Inline PWM current measurement
  • Bidirectional shunt measurements

Avoid if

  • Applications requiring common-mode voltage above 110 V
  • Systems requiring a gain other than the fixed 20 V/V option

Check before use

  • Confirm shunt dissipation at maximum current
  • Set REF1 and REF2 for the required output offset
  • Place a 0.1 µF bypass capacitor near VS and GND
