GENERAL DESCRIPTION
The SPT7862 contains two separate 10-bit CMOS analog-
to-digital converters that have sampling rates of up to 40
MSPS. Each device has its own separate clock and refer-
ence inputs so that they can be used independently in
multichannel applications or can be driven from the same
inputs for demanding quadrature demodulation and S-video
applications. On-chip track-and-hold and advanced propri-
etary circuit design in a CMOS process technology provide
very good dynamic performance.
The SPT7862 operates from a single +5 V supply. Digital
data outputs are user selectable at +3 or +5 V. Output data
format is straight binary.
The SPT7862 is available in a 64-lead TQFP package
(10 x 10 mm) over the industrial temperature range of
–40
°
C to +85
°
