AK4685 Description
The AK4685 is a single chip CODEC that integrates 4-channel ADC, 2-channel DAC and a stereo capacitor less headphone amplifier. The converters are designed with an Enhanced Dual Bit architecture for the ADC, and an Advanced Multi-Bit architecture for the DAC’s, enabling very low noise performance and achieving wide dynamic range. The differential analog inputs and outputs cancel noise on analog signal lines.
