Analog Input Selection (Bits 2:0)
Function:
These bits are used to select the input source for the PGA and ADC. Please see Table 15 below.
6.10 DAC Channel A Volume Control - Address 0Ah
See 6.11 DAC Channel B Volume Control - Address 0Bh
6.11 DAC Channel B Volume Control - Address 0Bh
6.11.1 Volume Control (Bits 7:0)
Function:
The digital volume control allows the user to attenuate the signal in 0.5 dB increments from 0 to
-127 dB. The Vol0 bit activates a 0.5 dB attenuation when set, and no attenuation when cleared. The
Vol[7:1] bits activate attenuation equal to their decimal equivalent (in dB). Example volume settings
are decoded as shown in Table Table 16. The volume changes are implemented as dictated by the
DACSoft and DACZeroCross bits in the DAC Control 2 register (see section 6.12.1).
