Because the RESET is an asynchronous control signal, small clicks and pops can be produced during the
application (the leading edge) of this control. However, when RESET is released, the transition from the hard
mute state back to normal operation is performed synchronously using a quiet sequence.
If a completely quiet reset sequence is desired, MUTE should be applied before applying RESET.

2.2.2 Power Down—PDN
The TAS5036A can be placed into the power-down mode by holding the PDN terminal low. When the
power-down mode is entered, both the PLL and the oscillator are shut down. Volume is immediately set to full
attenuation (there is no ramp down). The valid 16 outputs are immediately asserted low and the PWM outputs
are placed in the hard mute state. PDN initiates device power down without clock inputs. As long as the PDN
terminal is held low, the device is in the power-down (hard mute) state.
During power down, all I

C and serial data bus operations are ignored. Table 28 shows the device output
signals while PDN is active.

To place the device in total power-down mode, both RESET and power-down modes must be enabled. Prior
to bringing PDN high, RESET must be brought low for a minimum of 50 ns.
