CS53L21
ADCx 20 dB Digital Boost (ADCx_DBOOST)
Default: 0
0 - Disabled
1 - Enabled
Function:
Applies a 20 dB 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, the MICBIAS is output
on the AIN3B/MICIN2 pin. If set to ‘1’b, 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.

ADCX High-Pass Filter Enable (ADCX_HPFEN)
Default: 1
0 - High-pass filter is disabled
1 - High-pass filter is enabled
Function:
When this bit is set, the internal high-pass filter will be enabled for ADCx. When set to ‘0’, the high-pass filter
will be disabled. For DC measurements, this bit must be cleared to ‘0’.
