Datasheet

7.6. Audio Data Path

The ALC5616 provides 2-channel analog DACs for playback and 2-channel analog ADCs for recording.

7.6.1. Stereo Analog ADCs Record Path

There are two analog ADCs and with 2-channel recording path. You can use two analog microphones

pass to analog ADCs or stereo line inputs to analog ADCs.

The full scale input of analog ADC with 0dB path setting is around 0.7Vrms. In order to save power, the

left and right analog ADC can be powered down separately by setting pow_adc_l (MX-61[2]) and

pow_adc_r (MX-61[1]). And the volume control of the stereo ADC is also separately controlled by

ad_gain_l (MX-1C[14:8]) and ad_gain_r (MX-1C[6:0]).
