GENERAL DESCRIPTION
The AK4682 is a single chip CODEC that includes two channels of ADC and four channels of DAC. The ADC
outputs 24bit data and the DAC accepts up to 24bit input data. The ADC has the Enhanced Dual Bit
architecture with wide dynamic range. The DAC introduces the new developed Advanced Multi-Bit
architecture, and achieves wider dynamic range and lower outband noise. The AK4682 integrates stereo
selector supporting 2Vrms I/O. The AK4682 has a dynamic range of 96dB for ADC, 102dB for DAC and is well
suited for digital TV and home theater system.
