Description

The AD73311 is a complete front-end processor for general urpose applications including speech and telephony. It features 16-bit A/D conversion channel and a 16-bit D/A conversion hannel. Each channel provides 70 dB signal-to-noise ratio over voiceband signal bandwidth. The final channel bandwidth can e reduced, and signal-to-noise ratio improved, by external igital filtering in a DSP engine.

The AD73311 is suitable for a variety of applications in thespeech and telephony area including low bit rate, high quality ompression, speech enhancement, recognition and synthesis.

The low group delay characteristic of the part makes it suitable-for single or multichannel active control applications.The gains of the A/D and D/A conversion channels are pro-grammable over 38 dB and 21 dB ranges respectively. Anon-chip reference voltage is included to allow single supply operation. A serial port (SPORT) allows easy interfacing of-single or cascaded devices to industry standard DSP engines.The AD73311 is available in both 20-lead SOIC and SSOP ackages.
