WM8350
13 AUDIO CODEC SUBSYSTEM
13.1 GENERAL DESCRIPTION
w
The WM8350 includes a high-performance stereo CODEC. Analogue output buffers and input
amplifiers are integrated on-chip, enabling the WM8350 to connect directly to headphones and
microphones as well as line-in and line-out sockets.
The CODEC handles analogue-to-digital and digital-to-analogue conversion for audio signals, and
integrates programmable filtering. Analogue mixing capabilities are also provided.
Digital audio data is transferred to and from the audio CODEC through a dedicated audio interface
that supports a number of industry-standard data formats.
Electrical power is provided to the CODEC through the following pins:





DBVDD and DGND – for the CODEC’s audio interface
DCVDD and DGND – for the CODEC’s digital core
HPVDD and HPGND – for the analogue outputs
AVDD and REF_GND – for ADC and DAC references
AVDD and GND – for all other analogue functions (including input amplifiers and buffers,
ADC, DAC, and analogue mixers)
