DAC SDIN Source (Bit 7)
Function:
This bit is used to select the serial audio data source for the DAC as shown in
Digital Loopback (Bit 1)
Function:
When this bit is set, an internal digital loopback from the ADC to the DAC will be enabled. Please refer to
“Internal Digital Loopback” on page
Channel B PGA Gain (Bits 5:0)
Function:
See
Channel A PGA Gain (Bits 5:0)
Function:
Sets the gain or attenuation for the ADC input PGA stage. The gain may be adjusted from -12 dB to
+12 dB in 0.5 dB steps. The gain bits are in two’s complement with the Gain0 bit set for a 0.5 dB step.
Register settings outside of the ±12 dB range are reserved and must not be used. See
ample settings.
