GENERAL DESCRIPTION

The SPT7861 is a 10-bit monolithic, low-cost, ultralow-

power analog-to-digital converter capable of minimum

word rates of 40 MSPS. This is a pin-compatible improved

version of the SPT7860. The on-chip track-and-hold func-

tion assures excellent dynamic performance without the

need for external components. The input drive require-

ments are minimized due to the SPT7861’s low input

capacitance of only 5 pF.

Power dissipation is extremely low at only 160 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

SPT7861 is pin-compatible with an entire family of 10-bit,

CMOS converters (SPT7835/40/50/55/60/61), which sim-

plifies upgrades. The SPT7861 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 SPT7861 is available in 28-lead SOIC and 32-lead

small (7 mm square) TQFP packages over the commer-

cial temperature range.
