INA181A3IDCKR is a 100 V/V single-channel current-sense amplifier for bidirectional shunt-current measurement on buses up to 26 V common mode.

Best for

  • Bidirectional shunt-current measurement
  • High-side or low-side sensing up to 26 V common mode
  • Low-voltage ADC current-monitor inputs

Avoid if

  • The required common-mode voltage exceeds 26 V without external transient protection
  • The amplified shunt signal cannot fit within the available output swing
  • An integrated shunt resistor is required

Check before use

  • Confirm the 100 V/V gain matches the selected shunt resistor
  • Set REF appropriately for unidirectional or bidirectional operation
  • Place Kelvin connections close to the shunt resistor
  • Use a local 0.1 µF supply bypass capacitor
