Amplifiers

current-sense amplifierbidirectional100 V/V gainPWM rejection110 V common-modeSOT-23-8

INA241A4IDDFR is a high-precision, bidirectional shunt current-sense amplifier with 100 V/V gain and enhanced PWM rejection for switching systems up to 110 V common-mode.

Best for

  • PWM motor-drive current measurement
  • Bidirectional high-side or inline shunt sensing
  • Fast over-current monitoring

Avoid if

  • Applications needing gain other than 100 V/V
  • Common-mode voltage outside -5 V to 110 V
  • Systems without enough output headroom for the selected shunt

Check before use

  • Confirm output span against the supply rails
  • Set REF1 and REF2 for unidirectional or bidirectional operation
  • Place a 0.1 µF bypass capacitor close to VS and GND
