Amplifiers

current-sense amplifier200 V/V gain110 V common modeopen-drain comparatorVSSOP-8

INA310A4IDGKR is a precision 200 V/V current-sense amplifier for unidirectional high-side or low-side measurement, with a wide -4 V to 110 V common-mode range and an integrated overcurrent comparator.

Best for

  • Fast overcurrent detection
  • High-side current sensing up to 110 V common mode
  • 48 V power conversion and battery systems

Avoid if

  • Bidirectional current measurement is required with one amplifier
  • A negative differential shunt voltage can occur during normal operation

Check before use

  • Verify VOUT remains within its ground and supply swing limits
  • Select divider resistors with total resistance above 10 kΩ and preferably below 100 kΩ
  • Use Kelvin connections from the shunt resistor to the input pins
