MONO MIXER
MIXER OUTPUT INVERTERS
w
The mono mixer drives the MONO pin. The following signals can be mixed into MONO:
In a typical smartphone application, the MONO signal is a mix of the amplified microphone signal
(possibly with Automatic Gain Control) and (if enabled) an audio playback signal from the stereo
DAC or the auxiliary DAC.
Note that when selected the stereo input pairs LINEL/R and DACL/R are summed and attenuated by
-6dB so that 0dBFS signals on each channel sum to give a 0dBFS mono signal.
When not in use the mono mixer can be powered down using the Powerdown register bit MX
(register 3Ch, bit 0).
There are two general purpose mixer output inverters, INV1 and INV2. Each inverter can be selected
to drive HPMIXL, HPMIXR, SPKMIX, MONOMIX or { ( HPMIXL + HPMIXR ) / 2 }. The outputs of the
inverters can be used to generate complimentary signals (to drive BTL configured loads) and to
provide greater flexibility in output driver configurations. INV1 can be selected as the source for
SPKL, MONO and OUT3 and INV2 as the source for SPKR and OUT4.
The input source for each inverter is selected using INV1[2:0] and INV2[2:0] in register 1Eh (see
Table 31). When no input is selected the inverter is powered down.
