5. driving stereo headphones in single-ended configuration with two drivers, while the remaining two drivers are
connected in BTL configuration to an 8-
speaker.
The output stage architecture leading to the high power output drivers is shown in Figure 33, with the volume
control and mixing blocks being effectively identical to that shown in Figure 32. Note that each of these drivers
have a output level control block like those included with the line output drivers, allowing gain adjustment up to
+9dB on the output signal. As in the previous case, this output level adjustment is not intended to be used as a
standard volume control, but instead is included for additional fullscale output signal level control.
Two of the output drivers, HPROUT and HPLOUT, include a direct connection path for the stereo DAC outputs to
be passed directly to the output drivers and bypass the analog volume controls and mixing networks, using the
DAC_L2/R2 path. As in the line output case, this functionality provides the highest quality DAC playback
performance with reduced power dissipation, but can only be utilized if the DAC output does not need to route to
multiple output drivers simultaneously, and if mixing of the DAC output with other analog signals is not needed.
The direct connection path will attenuate the signal by a factor of 1 dB.
