INA290A3QDCKRQ1 is a 100 V/V automotive high-side current-sense amplifier for positive, unidirectional shunt-current measurement on rails up to 120 V common mode.

Best for

  • Automotive high-side current monitoring
  • Pump and motor current sensing
  • Fast overcurrent detection

Avoid if

  • Bidirectional current measurement is required
  • The measured rail exceeds 120 V common mode
  • A negative differential sense voltage is expected during normal operation

Check before use

  • Confirm 100 V/V gain suits the ADC input range
  • Calculate shunt dissipation at maximum load current
  • Use Kelvin routing from the shunt to IN+ and IN-
  • Place a 0.1 µF bypass capacitor near VS and GND
