on a separate supply. This circuit ensures that shutdown is disabled when powering up the LM4916 by either

allowing shutdown to be high before the LM4916 powers on (the microcontroller powers up first) or allows

shutdown to ramp up with VDD (the LM4916 powers up first). This will ensure the LM4916 powers up properly

and enters the correct mode of operation. Please note that the SE/BTL pin (Pin 8) should be tied to GND for

Single Ended mode, and to VDD for BTL mode.
