AK4685 Datasheet Multi-channel Codec

Manufacturer: AKM (Asahi Kasei Microdevices)

Overview: [AK4685] AK4685 Multi-channel CODEC with Differential Analog.

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.
