AD73311LARSZ

Product Summary

The AD73311LARSZ is a complete front-end processor for general purpose applications including speech and telephony. It features a 16-bit A/D conversion channel and a 16-bit D/A conversion channel. Each channel provides 70 dB signal-to-noise ratio over a voiceband signal bandwidth. The final channel bandwidth can be reduced, and signal-to-noise ratio improved, by external digital filtering in a DSP engine. The applications of the AD73311LARSZ include General Purpose Analog I/O, Speech Processing, Cordless and Personal Communications, Telephony, Active Control of Sound and Vibration, Data Communications.
