Datasheet Summary
[AK4685]
Multi-channel CODEC with Differential Analog I/O
GENERAL 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. Therefore, a stable system can be designed. The AK4685 has a dynamic range of 102dB for ADC, 106dB for DAC, and is well suited for digital TV and home theater systems.
