AD73322

The AD73322 is a dual front-end processor for general-purpose pplications including speech and telephony. It features two16-bit A/D conversion channels and two 16-bit D/A conversion channels. Each channel provides 77 B signal-to-noise ratio over a voiceband 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 Inter-face Circuits (SLICs).

The AD73322 is particularly suitable for a variety of applica-tions 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.
