Description

The AD73322L is a dual front-end processor for general pur-se applications including speech and telephony. It featurestwo 16-bit A/D conversion channels and two 16-bit D/A con-version channels. Each channel provides 78 dB signal-to-noiseratio over a voiceband signal bandwidth. It also features aninput-to-output gain network in both the analog and digitaldomains. This is featured on both codecs and can be used forimpedance matching or scaling when interfacing to SubscriberLine Interface Circuits (SLICs).The AD73322L is particularly suitable for a variety of applica-
tions in the speech and telephony area, including low bit rate,highqualitycompression,speechenhancement,
recognition andsynthesis. The low group delay characteristic of the part makesit suitable for single or multichannel active control applications.
