DVDD, and PVDD supply connections, as well AGND, DGND,
and PGND.
In addition, the ADAU1513 incorporates a built-in undervoltage
lockout logic on DVDD as well as PVDD. This helps detect
undervoltage operation and eliminates the need to have an
external mechanism to sense the supplies.
The ADAU1513 monitors the DVDD and PVDD supply
voltages and prevents the power stage from turning on if either
of the supplies are not present or below the operating threshold.
Therefore, if DVDD is missing or below the operating thresh-
old, for example, the power stage will not turn on, even if the
PVDD is present or vice versa.
Because this protection is only present on DVDD and PVDD
and not on AVDD, shorting both AVDD and DVDD externally
or generating AVDD and DVDD from one power source is
recommended. This ensures both AVDD and DVDD supplies
are tracking each other and avoids the need to monitor the
sequence with respect to PVDD. This also ensures minimal
pop and click during power-up.
When using separate AVDD and DVDD supplies, ensure that
both supplies are stable before unmuting or turning on the
power stage.
During power-up, it is recommended to keep STDN and MUTE
low to ensure that the power stage stays in high-Z mode.
Similarly, during shutdown, pulling MUTE to logic low before
pulling STDN down is recommended. However, where a fault
event occurs, the power stage will shut down to protect the part.
In this case, depending on the signal level, there is some pop at
the speaker.
During shutdown of the power supplies to reduce power
consumption, it is highly recommended to mute the amplifier
first, followed by pulling STDN low before shutting down any of
the supplies. After MUTE is pulled low, the power supplies can
be shut down in the following order: PVDD, DVDD, then
AVDD. Where AVDD and DVDD are generated from a single
source, ensure that PVDD is tuned off before DVDD and
AVDD, and after issuing MUTE and STDN.
