The device features low quiescent current (IQ), while still providing sufficient small-signal bandwidth to be usable in most applications. The quiescent current of the INA191 is only 43 µA (typical), while providing a small-signal bandwidth of 35 kHz in a gain of 100. The low IQ and good bandwidth allow the device to be used in many portable electronic systems without excessive drain on the battery. Because many applications only need to periodically monitor current, the INAx191 features an enable pin for each output that turns off the device until needed. When in the disabled state, the INAx191 typically draws 10 nA of total supply current per channel.
