Figure 31. Architecture of the output stage leading to the high power output drivers
The high power output drivers include additional circuitry to avoid artifacts on the audio output during power-on
and power-off transient conditions. The user should first program the type of output configuration being used in
Page-0/Reg-14, to allow the device to select the optimal power-up scheme to avoid output artifacts. The
power-up delay time for the high power output drivers is also programmable over a wide range of time delays,
from instantaneous up to 4-sec, using Page-0/Reg-42.
When these output drivers are powered down, they can be placed into a variety of output conditions based on
register programming. If lowest power operation is desired, then the outputs can be placed into a tri-state
condition, and all power to the output stage is removed. However, this generally results in the output nodes
drifting to rest near the upper or lower analog supply, due to small leakage currents at the pins. This then results
in a longer delay requirement to avoid output artifacts during driver power-on. In order to reduce this required
