DIGITAL AUDIO and MULTIMEDIA SOUND CODECs
AK4686
2ch ADC & 4ch DAC with Input Selector and Cap-less 2Vrms I/O
The AK4686 is a single chip audio CODEC that includes one stereo ADC and two stereo DACs in addition to the input selector and the line drivers. The interfaces of ADC/DAC can accept up to 24bit input data and support asynchronous operation. Both the input stereo selector and output drivers support ground reference I/O to remove AC-coupling capacitors and reducing external parts. The AK4686 has a dynamic range of 96dB for ADC, 100dB for DAC, and it is well suitable for digital TV and Home theater systems.
