Amplifiers

Current SenseAmplifierHigh Voltage

The INA281B5IDBVR is a high-precision, unidirectional current-sense amplifier from Texas Instruments, featuring a 500 V/V gain and a wide -4V to 110V common-mode input range.

Best for

  • High-speed overcurrent protection
  • Telecom power systems
  • Solenoid and valve control

Avoid if

  • Bidirectional current sensing is required

Check before use

  • Ensure the shunt resistor power dissipation is within limits for the 500 V/V gain setting.
