GENERAL DESCRIPTION
The SPT7734 is a 8-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 SPT7734'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 SPT7734 has
incorporated proprietary circuit design and CMOS process-
ing technologies to achieve its advanced performance. In-
puts and outputs are TTL/CMOS compatible to interface with
TTL/CMOS logic systems. Output data format is straight
binary.
The SPT7734 is available in 28-lead SOIC and 32-lead small
(7 mm square) TQFP packages over the commercial tem-
perature range.
