General Description
AD73322L General Description
The AD73322L is a dual front-end processor for general pur-se applications including speech and telephony. It features two 16-bit A/D conversion channels and two 16-bit D/A con-version channels. Each channel provides 78 dB 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 Interface Circuits (SLICs).The AD73322L is particularly suitable for a variety of applica-
tions in the speech and telephony area, including low bit rate,high quality compression,spee chenhancement,
recognition and synthesis. The low group delay characteristic of the part makes it suitable for single or multichannel active control applications.
