PGA_GAIN
CTRLR[3:0]
ADC input amplifier right gain settings. A 4-bit value to program the gain of the
input amplifier. There are nine settings, for a gain range from 0 to 24 dB in steps of
3 dB. The gain control of the PGA is independent for left and right. Default value 0000,
see Table 56.

PGA_GAIN
CTRLL[3:0]
ADC input amplifier left gain settings. A 4-bit value to program the gain of the input
amplifier. There are nine settings, for a gain range from 0 to 24 dB in steps of 3 dB.
The gain control of the PGA is independent for left and right. Default value 0000,
see Table 56.
