• Instrumentation
• Electronic Warfare
• Digital Communications
GENERAL DESCRIPTION
The SPT7824 A/D converter is a 10-bit monolithic converter
capable of word rates a minimum of 40 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 SPT7824
also provides a wide input voltage swing of ±2.0 volts.
The SPT7824 is available in 28-lead ceramic sidebrazed DIP,
PDIP and SOIC packages over the commercial, industrial and
military temperature ranges. Consult the factory for availabil-
ity of die and /833 versions.
