GENERAL DESCRIPTION
The SPT7835 is a 10-bit monolithic, low cost, ultralow power
analog-to-digital converter capable of minimum word rates of
5 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 SPT7835's low input capacitance of only 5 pF.
Power dissipation is extremely low at only 75 mW typical at
5 MSPS with a power supply of +5.0 V. The digital outputs
are +3 V or +5 V and are user selectable. The SPT7835 is pin-
ers (SPT7835/40/50/55/60/61) which simplifies upgrades.
BLOCK DIAGRAM
The SPT7835 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 SPT7835 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.
