The AD73322L is a dual front-end processor for generalpurpose applications, including speech and telephony. It features two 16-bit A/D conversion channels and two 16-bit D/A conversion channels. Each channel provides 78 dB signalto-noise ratio over a voice-band signal bandwidth. It also features an input-to-output gain network in both the analog and digital domains. This is featured on both codecs and can be used for impedance matching or scaling when interfacing to subscriber line interface circuits (SLICs). The AD73322L is particularly suitable for a variety of applications in the speech and telephony area, including low bit rate, high quality compression, speech enhancement, recognition, and synthesis. The low group delay characteristic of the part makes it suitable for single or multichannel active control applications.
