GENERAL DESCRIPTION
The SPT7840 is a 10-bit monolithic, low cost, ultralow power
analog-to-digital converter capable of minimum word rates
of 10 MSPS. The on-chip track-and-hold function assures
very good dynamic performance without the need for exter-
nal components. The input drive requirements are mini-
mized due to the SPT7840's low input capacitance of only
5 pF.
Power dissipation is extremely low at only 100 mW typical
(120 mW maximum) at 10 MSPS with a power supply of
+5.0 V. The digital outputs are +3 V or +5 V, and are user
selectable. The SPT7840 is pin-compatible with the entire
family of SPT 10-bit, CMOS converters (SPT7835/40/50/55/
60/61) which simplifies upgrades.
The SPT7840 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 SPT7840 is available in 28-lead 300 mil cerdip and
PDIP, 28-lead SOIC and 32-lead small (7 mm square) TQFP
packages over the commercial temperature range. For avail-
ability of extended temperature ranges and /883 processing
requirements, consult the factory.
