OUTPUT SIGNAL PATH

The WM8948 provides two Line Output mixers and two Speaker Output mixers. Multiple inputs to

each mixer provide a high degree of flexibility to route different signal paths to each of the four

analogue outputs.

The DAC outputs can be routed to the mixers either directly or in inverted phase. This makes it easy

to generate differential (BTL) or mono output signals.

The Auxiliary inputs AUX1/2 may be routed directly to the Speaker outputs, bypassing the Speaker

PGAs and mixers. This can be used to provide a fixed-gain signal path for a “PC Beep” or similar

application.

The output signal paths and associated control registers are illustrated in Figure 20.

Note that the speaker outputs are intended to drive a mono headset or speaker (in BTL

configuration). They are not designed to drive stereo speakers directly.
