Current-sense amplifiers

200 V/V gainBidirectional current senseEnhanced PWM rejection-5 V to 110 V common modeSOIC-8

INA241A5IDR is a 200 V/V bidirectional current-sense amplifier for shunt-based current measurement in PWM and high-voltage common-mode systems.

Best for

  • Bidirectional shunt current measurement
  • Inline motor-current sensing with PWM common-mode transitions
  • High-side or low-side current measurement

Avoid if

  • The required output exceeds the supply-dependent output swing limits
  • A different fixed gain is required without changing the shunt resistor
  • The system common-mode voltage exceeds -5 V to 110 V

Check before use

  • Confirm the 200 V/V gain matches the current range and ADC range
  • Set REF1 and REF2 for the required unidirectional or bidirectional output offset
  • Place a 0.1 µF bypass capacitor close to VS and GND
