| [AK4611] AK4611 4/8-Channel Audio CODEC GENERAL DESCRIPTION The AK4611 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. Fabricated on a low power process, the AK4611 operates off of a +3.3V analog supply and a +1.8V digital supply. The AK4611 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 AK4611 is available in an 80-pin LQFP package.
