GENERAL DESCRIPTION
The SPT7820 A/D converter is a 10-bit monolithic converter
capable of word rates of a minimum of 20 MSPS. On board
track/hold function assures excellent dynamic performance
without the need for external components. Drive require-
ment problems are minimized with an input capacitance of
only 5 pF.
Inputs and outputs are TTL compatible to interface with TTL
logic systems. An overrange output signal is provided to
indicate overflow conditions. Output data format is straight
binary. Power dissipation is very low at only 1.0 watt with
power supply voltages of +5.0 and -5.2 volts. The SPT7820
also provides a wide input voltage swing of
±2.0 volts.
The SPT7820 is available in 28-lead ceramic sidebrazed DIP,
PDIP and SOIC packages over the commercial, industrial
and military temperature ranges. Contact the factory for
availability of die and /883 versions.
