OUTPUT SIGNAL PATH

The WM9093 output mixers provide a high degree of flexibility, allowing configurable operation of

multiple signal paths through the device to a variety of analogue outputs. The outputs comprise a

ground referenced headphone driver and Class D/AB loudspeaker driver. See “Analogue Outputs” for

further details of these outputs.

The WM9093 output signal paths and control registers are illustrated in Figure 3.

The output mixers and drivers can be independently enabled and disabled as described in Table 4.

See “Power Sequences and Pop Suppression Control” for details of additional control bits relating to

the Headphone Output configuration.

Note that, when using the ‘Voice Bypass’ inputs on pins IN3+ and IN3-, these signals can be routed to

the Speaker output without enabling the Speaker mixer or the Speaker PGA. This provides a low-

power configuration, bypassing the input and output mixer circuits.
