WM8990
Production Data
INPUT SIGNAL PATH
The WM8990 has eight highly flexible analogue input channels, configurable in many combinations
of the following:
1. Up to four pseudo-differential or single-ended microphone inputs
2. Up to eight mono line inputs or 4 stereo line inputs
3. Mono input from external voice CODEC
4. Two fully balanced differential inputs
These inputs may be mixed together or independently routed to different combinations of output
drivers. An internal record path is provided at the input mixers to allow DAC output to be mixed with
the input signal path (e.g. for karaoke or voice call recording).
The WM8990 input signal paths and control registers are illustrated in Figure 16.
