GENERAL DESCRIPTION
The SPT7860 is a 10-bit monolithic, low cost, ultralow power
analog-to-digital converter capable of minimum word rates
of 40 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 SPT7860's low input capacitance of only
5 pF.
Power dissipation is extremely low at only 175 mW typical at
40 MSPS with a power supply of +5.0 V. The digital outputs
are +3 V or +5 V, and are user selectable. The SPT7860 is
pin-compatible with the entire family of SPT 10-bit, CMOS
converters (SPT7835/40/50/55/60/61) which simplifies up-
grades. The SPT7860 has incorporated proprietary circuit
design and CMOS processing technologies to achieve its
advanced performance. Inputs and outputs are TTL/CMOS
compatible to interface with TTL/CMOS logic systems. Out-
put data format is straight binary.
The SPT7860 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.
