and right DACs (see the Signal Routing section). The
right- and left-channel input data is summed without
attenuation and may overdrive the input filter, causing
distortion, when the input signals are large. The sum of
the stereo input signal should not exceed the dynamic
range of the filter, typically 0dBFS digital full scale.
When operating in a voice mode with the primary S1
interface, the digital signal data is input to the left chan-

nel without summing since the incoming data is
assumed to be mono. Adjust PGADS1 and PGADS2
(register 0x0C and 0x0D) to program the gain for the
primary and secondary digital audio interfaces.
Independent gain adjustment for each interface allows
level-matching of different digital signal sources or fade
adjustment between two signal sources.
