Amplifiers

Current SenseZero-DriftBidirectionalLow Power

The INA190A3IDDFR is a high-precision, low-power, bidirectional current-sense amplifier with a fixed gain of 100V/V, ideal for battery-powered applications requiring microamp-level current monitoring.

Best for

  • Battery-powered systems
  • Precision current monitoring
  • High-side current sensing

Avoid if

  • Applications requiring high-speed transient response beyond the device bandwidth
  • Systems where the supply voltage is significantly lower than the required output range

Check before use

  • Shunt resistor power rating
  • PCB layout for Kelvin connections
  • Reference voltage (REF) pin configuration
