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 func-
tion assures very good dynamic performance without the
need for external components. The input drive require-
ments are minimized 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 out-
puts are +3 V or +5 V, and are user selectable. The
SPT7860 is pin-compatible with an entire family of 10-bit,
CMOS converters (SPT7835/40/50/55/60/61), which sim-
plifies upgrades. The SPT7860 has incorporated propri-
etary 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. Output data format is straight binary.
The SPT7860 is available in 28-lead SOIC and 32-lead
small (7 mm square) TQFP packages over the commer-
cial temperature range.
