Datasheet
The AK4614 is a single chip audio CODEC that includes six ADC channels and twelve 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
AK4614 operates off of a +3.3V analog supply and a +1.8V digital supply. The AK4614 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 AK4614 is available in an 80-pin LQFP package.
