AOUT3 Select

These bits are used to select the analog output source.

6.15

ADCx Volume Control: ADCA (Address 10h) & ADCB (Address 11h)

The level for each channel of the ADC can be adjusted in 0.5 dB increments as dictated by the ADC Soft

and Zero Cross bits (ADC_SOFT) from +12 to -84 dB. Levels are decoded in two’s complement, as shown

in the table below.

6.16

DAC1x Volume Control: DAC1A (Address 12h) & DAC1B (Address 13h)

The level for each channel of DAC1 output can be adjusted in 0.5 dB increments as dictated by the DAC1

Soft and Zero Cross bits (DAC1_SOFT & DAC1_ZC) from 0 to -127.5 dB. Levels are decoded as unsigned,

as shown in the table below.
