Amplifiers

current-sense amplifierbidirectional50 V/V gain26 V common modeSC70-6

INA181A2IDCKR is a 50 V/V, single-channel bidirectional current-sense amplifier for low-side and high-side current measurement up to 26 V common mode.

Best for

  • Compact current monitoring
  • High-side or low-side sensing
  • Bidirectional battery or motor current measurement

Avoid if

  • Common-mode voltage exceeds 26 V without external transient protection
  • Required output bandwidth exceeds the 210 kHz typical A2 bandwidth

Check before use

  • Calculate shunt power dissipation
  • Check output headroom at peak current
  • Use Kelvin connections to the shunt resistor
  • Place a 0.1 µF bypass capacitor close to VS and GND
