AD73311  
FEATURES  
GENERAL DESCRIPTION  
16-Bit A/D Converter  
16-Bit D/A Converter  
Programmable Input/Output Sample Rates  
75 dB ADC SNR  
70 dB DAC SNR  
The AD73311 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.  
64 kS/s Maximum Sample Rate  
–90 dB Crosstalk  
Low Group Delay (25 s Typ per ADC Channel,  
50 s Typ per DAC Channel)  
Programmable Input/Output Gain  
Flexible Serial Port which Allows up to 8 Devices  
to Be Connected in Cascade  
Single (+2.7 V to +5.5 V) Supply Operation  
50 mW Max Power Consumption at 2.7 V  
On-Chip Reference  
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 pro-  
grammable over 38 dB and 21 dB ranges respectively. An  
on-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.  
20-Lead SOIC/SSOP Package  
APPLICATIONS  
General Purpose Analog I/O  
Speech Processing  
Cordless and Personal Communications  
Telephony  
The AD73311 is available in both 20-lead SOIC and SSOP  
packages.
