OUTPUT SIGNAL PATH
w
The WM8903 has one pair of analogue mixers (the “left” and right” mixers) feeding the headphone
outputs HPOUTL and HPOUTR as well as the line outputs LINEOUTL and LINEOUTR, and a
separate pair of mixers (the “speaker mixers”) feeding the differential line outputs LON/LOP and
RON/ROP (these pins are in the “Analogue Outputs” section).
The output signal paths and associated control registers are illustrated in Figure 33.
