The 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 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.Features
