GENERAL DESCRIPTION
The SPT7852 has two 10-Bit CMOS analog-to-digital con-
verters that can sample data at speeds up to 20 MSPS. It
has excellent low noise performance with a very low typical
power dissipation of only 160 mW—that’s the total power
for bothconverters. The SPT7852 uses a dual configuration
of the proprietary circuit design found in our 10-bit CMOS
single converter family, to achieve its high performance in a
CMOS process.
The SPT7852 is specifically designed for video decoding
applications and is ideal for S-video decoding and decoding
of multiple composite video sources. It also has excellent
application in the area of coherent I/Q demodulation in such
applications as QAM demodulation and TV set-top box con-
verters.
Inputs and outputs are TTL/CMOS-compatible to interface
with TTL/CMOS-logic systems. Output data format is select-
able for either straight binary or two’s complement. The
SPT7852 is available in a 44L TQFP package in commercial
and industrial temperature ranges. It is also available in die
form. For availability of extended temperature ranges,
please contact the factory.
