GENERAL DESCRIPTION
The AD73311L 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
fi
nal channel bandwidth can
be reduced, and signal-to-noise ratio improved, by external
digital
fi
ltering in a DSP engine.
The AD73311L 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 program-
mable 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 cas-
caded devices to industry standard DSP engines.
The AD73311L is available in 20-lead SOIC, SSOP and
TSSOP packages.
