Notes:
1. The Passthrough volume control is realized using a combination of the PGA volume control settings
(“PGAx Volume” on page 56) and the headphone amplifier volume control settings (hidden). When
passthrough is enabled and the PGA to ADC path is selected, the signal seen by the ADC will change
depending on the passthrough volume setting.
