INA190A2QDDFRQ1 is a 50 V/V, AEC-Q100 Grade 1 current-sense amplifier for bidirectional shunt-current measurement on rails up to 40 V.

Best for

  • Automotive low-power current monitoring
  • High-side or low-side shunt sensing
  • Bidirectional battery charge and discharge measurement

Avoid if

  • The common-mode voltage can exceed 40 V in normal operation
  • A package without an ENABLE pin is required
  • The output cannot accommodate REF-offset bidirectional signaling

Check before use

  • Maximum shunt voltage and output headroom
  • Transient protection for input voltages outside absolute maximum ratings
  • ADC input settling and filtering requirements
