AD73311ARSZ Datasheet PDF - ADI

●The AD73311ARSZ is a CMOS Analog 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 70dB signal-to-noise ratio over a voice band signal bandwidth. The final channel bandwidth can be reduced and signal-to-noise ratio improved, by external digital filtering in a DSP engine. The AD73311 is suitable for a variety of applications 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. The gains of the A/D and D/A conversion channels are programmable over 38dB and 21dB ranges respectively. An on-chip reference voltage is included to allow single supply operation.
