ADC Single Volume Control (ADC_SNGVOL)
Default: 0
0 - Disabled
1 - Enabled
Function:
The individual PGA Volume (PGAx_VOLx) and ADC channel attenuation (ADCx_ATTx) levels are indepen-
dently controlled by their respective control registers when this function is disabled. When enabled, the vol-
ume on both channels is determined by the ADCA Attenuator Control register, or the PGAA Control register,
and the ADCB Attenuator and PGAB Control registers are ignored.
ADCx 20dB Digital Boost (ADCx_DBOOST)
Default: 0
0 - Disabled
1 - Enabled
Function:
Applies a 20dB digital gain to the input signal on ADC channel x, regardless of the input path.
MIC Bias Select (MICBIAS_SEL)
Default: 0
0 - MICBIAS on AIN3B/MICIN2 pin
1 - MICBIAS on AIN2B pin
Function:
Determines the output pin for the internally generated MICBIAS signal. If set to ‘0’b, then the MICBIAS is
output on the AIN3B/MICIN2 pin. If set to ‘1’b, then the MICBIAS is output on the AIN2B pin.
MIC Bias Level (MICBIAS_LVL[1:0])
Default: 00
00 - 0.8 x VA
01 - 0.7 x VA
10 - 0.6 x VA
11 - 0.5 x VA
Function:
Determines the output voltage level of the MICBIAS output.
MIC X Preamplifier Boost (MICX_BOOST)
Default: 0
0 - +16 dB Gain
1 - +32 dB Gain
Function:
Determines the amount of gain applied to the microphone preamplifier for channel x.
