Figure 4. Relative Global Gain
The ADC gain is dependent on MCLK frequency (not on DCLK frequency) and ADC resolution. The default
global gain is set for typical MCLK frequency (12MHz) and 10-bit ADC. When the frequency and ADC resolution
is changed, the global gain should be changed to maintain the resulting gain over unity for assuring appropriate
ADC conversion range. The recommended minimum global gain setting depending on ggo_en and adcres is
shown in figure 5 and table 2.
