Amplifiers

Current SenseAmplifierHigh-SideLow-Side

The INA281A1IDBVR is a high-precision, 20 V/V gain current-sense amplifier with a wide -4 V to 110 V common-mode range, ideal for high-side and low-side current monitoring in industrial and telecom applications.

Best for

  • High-side and low-side current sensing
  • Fast overcurrent protection
  • Half-bridge applications

Avoid if

  • Bidirectional current sensing is required (this is a unidirectional device)

Check before use

  • Ensure the shunt resistor power dissipation is within limits
  • Verify the common-mode voltage range matches your application
