The A/D and D/A conversion channels feature programmable  
input/output gains with ranges of 38 dB and 21 dB respectively.  
An on-chip reference voltage is included to allow single-supply  
operation. This reference is programmable to accommodate  
either 3 V or 5 V operation.  
GENERAL DESCRIPTION  
The AD73322 is a dual front-end processor for general-purpose  
applications including speech and telephony. It features two  
16-bit A/D conversion channels and two 16-bit D/A conversion  
channels. Each channel provides 77 dB signal-to-noise ratio  
over a voiceband signal bandwidth. It also features an input-to-  
output gain network in both the analog and digital domains.  
This is featured on both codecs and can be used for impedance  
matching or scaling when interfacing to Subscriber Line Inter-  
face Circuits (SLICs).  
The sampling rate of the codecs is programmable with four  
separate settings, offering 64 kHz, 32 kHz, 16 kHz and 8 kHz  
sampling rates (from a master clock of 16.384 MHz).  
A serial port (SPORT) allows easy interfacing of single or cas-  
caded devices to industry standard DSP engines. The SPORT  
transfer rate is programmable to allow interfacing to both fast  
and slow DSP engines.  
The AD73322 is particularly suitable for a variety of applica-  
tions 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 AD73322 is available in 28-lead SOIC and 44-lead LQFP  
packages.
