Figure 44. Playback Signal Path
OUTPUT SIGNAL PATHS
The outputs of the ADAU1761 can be configured as a variety of
differential or single-ended outputs. All analog output pins are
capable of driving headphone or earpiece speakers. There are
selectable output paths for stereo signals or a downmixed mono
output. The line outputs can drive a load of at least 10 kΩ or can
be put into HP mode to drive headphones or earpiece speakers.
The analog output pins are biased at AVDD/2.
With a 0 dBFS digital input and AVDD = 1.8 V, the full-scale
output level is 500 mV rms; when AVDD = 3.3 V, the full-scale
output level is 920 mV rms.
Signals are inverted through the mixers and volume controls.
The result of this inversion is that the polarity of the differential
outputs and the headphone outputs is preserved. The single-
ended mono output is inverted. The DACs are noninverting.
Routing Flexibility
The playback path contains five mixers (Mixer 3 to Mixer 7)
that perform the following functions:
Mix signals from the record path and the DACs.
Mix or swap the left and right channels.
Mix a mono signal or generate a common-mode output.
Mixer 3 and Mixer 4 are dedicated to mixing signals from the
record path and the DACs. Each of these two mixers can accept
signals from the left and right DACs, the left and right input
mixers, and the dedicated channel auxiliary input. Signals
coming from the record path can be boosted or cut before the
playback mixer.
For example, the MX4G2[3:0] bits set the gain from the output
of Mixer 2 (right record channel) to the input of Mixer 4, hence
the naming convention.
Signals coming from the DACs have digital volume attenu-
ation controls set in Register R20 (left input digital volume
register, Address 0x401A) and Register R21 (right input digital
volume register, Address 0x401B).
