GENERAL DESCRIPTION
The SPT7920 A/D converter is the industry's first 12-bit
monolithic analog-to-digital converter capable of sample
rates greater than 10 MSPS. On board input buffer and
track/hold function assures excellent dynamic perfor-
mance without the need for external components. Drive
requirement problems are minimized with an input ca-
pacitance of only 5 pF.
Logic inputs and outputs are TTL. An overrange output
signal is provided to indicate overflow conditions. Output

data format is straight binary. Power dissipation is very low
at only 1.1 watts with power supply voltages of +5.0 and
-5.2 volts. The SPT7920 also provides a wide input voltage
range of
±2.0 volts.
The SPT7920 is available in 32-lead ceramic sidebrazed
DIP and 44-lead cerquad packages over the commercial
temperature range. Consult the factory for availability of die,
military temperature and /883 versions.
