AK4629

High Performance Multi-channel Audio CODEC

GENERAL DESCRIPTION

The AK4629 is a single chip audio CODEC that includes four ADC channels and eight DAC channels.

The converters are designed with Enhanced Dual Bit architecture for the ADC’s, and Advanced Multi-Bit

architecture for the DAC, enabling very low noise performance. The AK4629 ADC supports both

single-ended and differential inputs and outputs. A wide range of applications can be realized, including

home theater, pro audio and car audio. The AK4629 is available in a 48-pin LQFP package.
