AOUTX Volume Control (Addresses 08h- 0Fh)

AINX Volume Control (Address 11h-14h)
Volume Control (AOUTX_VOL[7:0])
Default = 00h
Function:
The AOUTx Volume Control registers allow independent setting of the signal levels in 0.5 dB increments
from 0 dB to -127.5 dB. Volume settings are decoded as shown in
plemented as dictated by the Soft and Zero Cross bits (DAC_SZC[1:0]). All volume settings less than -
127.5 dB are equivalent to enabling the AOUTx_MUTE bit for the given channel.
Default = 0
0 - Disabled
1 - Enabled
Function:
When enabled, these bits will invert the signal polarity of their respective channels.
Default = 00h
Function:
The level of the analog inputs can be adjusted in 0.5 dB increments as dictated by the ADC Soft and Zero
Cross bits (ADC_SZC[1:0]) from +24 to -64 dB. Levels are decoded in two’s complement, as shown in
