DAC Channel Mute (Address 07h)
AOUTX Volume Control (Addresses 08h- 0Fh)
Mute ADC Serial Port (MUTE ADC_SP)
Default = 0
0 - Disabled
1 - Enabled
Function:
When enabled, the ADC Serial Port will be muted.
Independent Channel Mute (AOUTX_MUTE)
Default = 0
0 - Disabled
1 - Enabled
Function:
The respective Digital-to-Analog converter outputs of the CS42448 will mute when enabled. The quies-
cent voltage on the outputs will be retained. The muting function is affected by the DAC Soft and Zero
Cross bits (DAC_SZC[1:0]). When all channels are muted, the MUTEC pin will become active.
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
implemented 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.
