WM9714L MONO SPEAKER
Figure 37 shows a typical output configuration compatible with the WM9712 for mono speaker with
headphones, ear speaker and hands-free operation. The table shows suggested mixer outputs to
select for each output PGA for a given operating scenario. (Note the inverted mixer outputs can be
achieved using the mixer output inverters INV1 and INV2).
When using this configuration note that AVDD, HPVDD and SPKVDD must all be at the same
voltage to achieve the best performance.
