GENERAL DESCRIPTION
The SPT7850 is a 10-bit monolithic, low cost, ultra-low power
analog-to-digital converter capable of minimum word rates of
20 MSPS. The on-chip track-and-hold function assures very
good dynamic performance without the need for external
components. The input drive requirements are minimized
due to the SPT7850's low input capacitance of only 5 pF.
Power dissipation is extremely low at only 140 mW typical
(165 mW maximum) at 20 MSPS with a power supply of
+5.0 V. The digital outputs are +3 V or +5 V, and are user
selectable. The SPT7850 is pin-compatible with the entire
family of SPT 10-bit, CMOS converters (SPT7835/40/50/55/
60/61) which simplifies upgrades.
The SPT7850 has incorporated proprietary circuit design
and CMOS processing technologies to achieve its advanced
performance. Inputs and outputs are TTL/CMOS-compat-
ible to interface with TTL/CMOS-logic systems. Output data
format is straight binary.
The SPT7850 is available in 28-lead 300 mil cerdip and PDIP,
28-lead SOIC and 32-lead small (7 mm square) TQFP
packages over the temperature range. For availability of
extended temperature ranges and /883 processing require-
ments, consult the factory.
