Amplifiers

Current SenseAmplifierHigh VoltagePrecision

The INA281A3IDBVR is a high-precision current-sense amplifier from Texas Instruments, offering a 100 V/V fixed gain and a wide -4V to 110V common-mode range.

Best for

  • Telecom infrastructure
  • Server power supplies
  • Solenoid and valve control

Avoid if

  • Bidirectional current sensing is required (this is unidirectional only).

Check before use

  • Ensure the shunt resistor power dissipation is within limits for your maximum current.
