Description

The AK4532 is a low-cost high-quality 16-Bit CODEC designed specifically for Internet Boxes, Network PCs, and to interface with audio/video controller ICs for standard PC applications. AKM's AK4532 serial interface mode simplifies the design process on existing and new audio projects. The converters can have a range of 4 to 50 kHz. For voice mail applications, an internal 26 dB microphone preamp has been added and because of the internal input mixer, music or other sounds can easily be mixed with voice.
