Amplifiers

100 V/V gain-4 V to 110 V common modeOpen-drain comparator0.6 V referenceVSSOP-8Unidirectional sensing

INA310A3IDGKR is a 100 V/V precision current-sense amplifier with a wide -4 V to 110 V common-mode range and an integrated open-drain overcurrent comparator.

Best for

  • Precision current measurement with high common-mode voltage
  • Fast overcurrent-alert circuits
  • High-side or low-side unidirectional sensing

Avoid if

  • Bidirectional current measurement is required with one amplifier
  • Negative differential shunt voltage is expected during normal operation
  • Required output range exceeds the selected supply-voltage swing

Check before use

  • Confirm the 2.7 V to 20 V supply range.
  • Keep IN+ and IN- within the specified common-mode and differential limits.
  • Use an external divider to set the comparator trip current.
  • Confirm CMPOUT pull-up voltage and reset/latch behavior.
