AK4687 - Asynchronous Stereo Audio CODEC

Description

The AK4687 is a stereo audio CODEC with 2-channel input selector and a line driver.

The interfaces of ADC/DAC can accept up to 24bit input data and support asynchronous operation.

The input range of the pre-amplifier, that supports 3ch stereo inputs, is selectable by external resistors.

[AK4687] AK4687 Asynchronous Stereo CODEC with Capless Stereo Selector GENERAL DESCRIPTION The AK4687 is a stereo audio CODEC with 2-channel input selector and a line driver. The interfaces of ADC/DAC can accept up to 24bit input data and support asynchronous operation. The input range of the pre-amplifier, that supports 3ch stereo inputs, is selectable by external resistors. Both the input stereo selector and output drivers support ground reference 2Vrms In/Output, making it possible to remove AC-coupling capacitors and reducing external parts. The AK4687 has a dynamic range of 99dB for ADC, 105dB for DAC. It is well suitable for digital recording systems, digital TVs, Blu-ray recorders and Home theater systems.
