The WN8031F integrate a low power, flexible and highly integrated stereo audio 

CODEC. It features stereo ADC with microphone inputs, and stereo DAC with 

headphone playback. It contains on-chip regulator and built-in programmable gain 

amplifiers (PGAs) for robust performance and operation. The CODEC transmits and 

receives 16-24bit audio data via standard master or slave mode digital audio

interface (DAI) such as in I2S format. It takes flexible master clock frequencies of 

12.288MHz, 11.2896MHz or 24MHz to support super wide band voice/audio 

processing with effective sampling frequencies (Fs) at 8kHz, 12kHz, 16kHz, 32 kHz, 

44.1kHz, 48kHz and 96kHz.

The stereo ADC recording path takes analog microphone inputs in differential 

configuration to enable multiple recording paths. The microphone input signals can 

be boosted by digitally-controlled stereo microphone PREAMP, followed by 6-bit 

internal programmable gain controlling (PGA). The converted outputs are 16-22bit 

PCM (pulse-code modulation) data and transferred via I2S interface.

The stereo DAC playback path converts 16-22bit audio data to analog audio signals 

with built-in stereo 6-bit gain amplifiers at 0.75dB/step fine tune resolution. The 

converted audio data are then processed to drive off-chip stereo headphones.

The codec operates at 3.3V for analog core and 1.2V for digital core in normal 

operation. On-chip voltage regulation and bias current enables better PSRR and noise 

rejection performance suitable for seamless SOC integration, where high frequency 

activities may couple significant ground bounce / substrate noise to the IP's analog 

core.
