AK4529

High Performance Multi-channel Audio CODEC

GENERAL DESCRIPTION

The AK4529 is a single chip CODEC that includes two channels of ADC and eight 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. 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 AK4529 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 AK4112A. The AK4529 is available in a small 44pin LQFP package which will reduce system space.

*AC-3 is a trademark of Dolby Laboratories.
