The AK4683 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 AK4683 also has digital audio

receiver (DIR) and transmitter (DIT) compatible with 192kHz, 24bits. The DIR can automatically detect a

Non-PCM bit stream such as Dolby Digital (AC-3)*. The AK4683 has a dynamic range of 100dB for ADC,

106dB for DAC and is well suited for digital TV and home theater system.

* Dolby Digital (AC-3) is a trademark of Dolby Laboratories.
