Overview
[AK4612] AK4612 6/8-Channel Audio CODEC GENERAL DESCRIPTION The AK4612 is a single chip audio CODEC that includes six 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.
Fabricated on a low power process, the AK4612 operates off of a +3.
3V analog supply and a +1.
8V digital supply.
The AK4612 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 AK4612 is available in an 80-pin LQFP package.
