TYPICAL OUTPUT CONFIGURATIONS

The WM9713L has three outputs capable of driving loads down to 16

Ω (headphone / line drivers) –

HPL, HPR and MONO - and four outputs capable of driving loads down to 8

Ω (loudspeaker / line

drivers) – SPKL, SPKR, OUT3 and OUT4. The combination of output drivers, mixers and mixer

inverters means that many output configurations can be supported. Below are some examples of

typical output configurations for smartphone applications.

STEREO SPEAKER

Figure 43 shows a typical output configuration for stereo speakers 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).
