The AMC1411 features a shutdown option which is an active high input. Resistor R5 is installed by default and allows for normal operation of the AMC1411. When the resistor is removed, the SHTDN pin can be controlled externally via J3.2 to shutdown the AMC1411. When shutdown, the AMC1411 enters into a low-power mode by means of an internal pullup resistor for battery-powered or other power-sensitive applications.
