Description

The AK4628AVQ is a single chip CODEC that includes two channels of ADC and eight channels of DAC. The ADC outputs 24-bit data and the DAC accepts up to 24-bit input data. The ADC has the Enhanced Dual Bit architecture with wide dynamic range. The DAC introduces the newly developed Advanced Multi-Bit architecture, and achieves wider dynamic range and lower outband noise. An auxiliary digital audio input interface maybe used instead of the ADC for passing audio data to the primary audio output port. Control may be set directly by pins or programmed through a separate serial interface.
The AK4628AVQ has a dynamic range of 102dB for ADC, 106dB for DAC and is well suited for digital surround for home theater and car audio. An AC-3 system can be built with a IEC60958 (SPDIF) receiver such as the AK4113VF. The AK4628AVQ is available in a small 44-pin LQFP package which will reduce system space.
*AC-3 is a trademark of Dolby Laboratories.
