Part Details:

a Low Cost, Low Power CMOS General Purpose Analog Front End AD73311L FEATURES GENERAL DESCRIPTION 16-Bit A/D Converter The AD73311L is a complete front-end processor for general 16-Bit D/A Converter purpose applications including speech and telephony. It features Programmable Input/Output Sample Rates a 16-bit A/D conversion channel and a 16-bit D/A conversion 76 dB ADC SNR channel. Each channel provides 70 dB signal-to-noise ratio over 77 dB DAC SNR a voiceband signal bandwidth. The final channel bandwidth can Programmable Sampling Rate be reduced, and signal-to-noise ratio improved, by external 64 kS/s Maximum Sample Rate digital filtering in a DSP engine. ­90 dB Crosstalk The AD73311L is suitable for a variety of applications in the Low Group Delay (25 ms Typ per ADC Channel, speech and telephony area, including low bit rate, high quality 50 ms Typ per DAC Channel) compression, speech enhancement, recognition and synthesis. Programmable Input/Output Gain The low group delay characteristic of the part makes it suitable Flexible Serial Port Which Allows Up to Eight Devices for single or multichannel active control applications. to Be Connected in Cascade Single (+3 V) Supply Operation The gains of the A/D and D/A conversion channels are program- 33 mW Max Power Consumption at 2.7 V mable over 38 dB and 21 dB ranges respectively. An on-chip On-Chip Reference reference voltage is included to allow single supply operation. 20-Lead SOIC/SSOP/TSSOP Packages A serial port (SPORT) allows easy interfacing of single or cas-caded devices to industry standard DSP engines. APPLICATIONS The AD73311L is available in 20-lead SOIC, SSOP and General Purpose Analog I/O TSSOP packages.
