[AK4682] Multi-channel CODEC with 2Vrms Stereo Selector 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 96d B for ADC, 102d B for DAC and is well suited for digital TV and home theater system.
