AINL (pin 3 or C2) and AINR (pin 4 or B2) are inputs to Mixer P and Mixer M along with the DAC output. Also AINL and AINR can be configured inputs to HP driver. Page1 / register 12 provides control signals for determining the signals routed through Mixer P, Mixer M and HP driver. Input of Mixer P can be attenuated by Page1 / register 24, input of Mixer M can be attenuated by Page1 / register 25 and input of HP driver can be attenuated by Page1 / register 22. Also AINL and AINR can be configured to a monaural differential input with use Mixer P and Mixer M by Page1 / register 12 setting. All the options can be viewed in the functional block diagram, Figure 3-6.
