Amplifiers

Current SenseAmplifierBidirectionalTI

The INA181A4IDBVR is a high-precision, bidirectional current-sense amplifier with a fixed gain of 200V/V, ideal for space-constrained monitoring applications.

Best for

  • Motor control
  • Battery management systems
  • Power supply monitoring

Avoid if

  • Applications requiring extremely high bandwidth (>350kHz)
  • Multi-channel requirements (use INA2181 or INA4181 instead)

Check before use

  • Ensure the shunt resistor is sized correctly for the 200V/V gain to avoid output saturation.
