Current-sense amplifiers

INA185-Q1INA185A120 V/V gain26 V common modeAEC-Q100SC70bidirectional current sensing

INA185A1QDCKRQ1 is an automotive-qualified 20 V/V bidirectional shunt-current amplifier for systems with up to 26 V input common-mode voltage.

Best for

  • Automotive 12 V current monitoring
  • High-side or low-side shunt sensing
  • Bidirectional battery or motor-current measurement

Avoid if

  • The output must exceed the 2.7 V to 5.5 V supply range
  • A gain other than fixed 20 V/V is required
  • Input common-mode voltage can exceed 26 V without external transient protection

Check before use

  • Confirm maximum shunt voltage and output swing margins.
  • Use a stable low-impedance REF source for bidirectional measurement.
  • Place a 0.1 µF bypass capacitor close to VS and GND.
