INA241A1QDGKRQ1 is a 10 V/V automotive bidirectional current-sense amplifier for current measurement on rails with common-mode voltages from -5 V to 110 V.

Best for

  • Automotive inline motor-current sensing
  • PWM-switched motor or solenoid systems
  • Bidirectional high-side, low-side, or inline shunt sensing

Avoid if

  • Applications requiring an integrated shunt resistor
  • Systems outside the -5 V to 110 V input common-mode range
  • Applications requiring a gain other than 10 V/V without external signal conditioning

Check before use

  • Confirm shunt resistor power rating and Kelvin routing
  • Keep output within the specified output swing limits
  • Configure REF1 and REF2 for unidirectional or bidirectional measurement
  • Place a 0.1 µF bypass capacitor close to VS and GND
