Audio Codec Block Diagram
Figure 10: Audio Codec Input and Output Stages
FSC-BT806B audio codec uses a fully differential architecture in the analogue signal path, which resultsin low noise
sensitivity and good power supply rejection while effectively doubling the signal amplitude. It operatesfrom a dual
power supply, VDD_AUDIO(internal) for the audio circuits and VDD_AUDIO_DRV (internal)for the audio driver circuits.
ADC
The picture aboveshows the FSC-BT806B consists of 2 high-quality ADCs
Each ADC has a second-order Sigma-Delta converter.
Each ADC is a separate channel with identical functionality.
There are 2 gain stages for each channel, 1 of which is an analogue gain stage and the other is a
digitalgain stage
