The analog mixer, which uses the mixer input of the FSDAC, can mix a signal into the FSDAC output signal via an AVC
unit (see Fig.11). The mixer can be used to mix a signal into the FSDAC output signal and play it via the headphone driver
without the complete coder-decoder running. The analog control range is 0 to −64.5 dB with a gain of 16.5 dB, and mutes
in steps of 1.5 dB (so actually the range is from +16.5 dB to −48 dB plus mute).
