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 function assures ex-
cellent dynamic performance without the need for external
components. The input drive requirements 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 outputs
are +3 V or +5 V, and are user selectable. The SPT7861 is

pin compatible with the entire family of SPT 10-bit, CMOS
converters (SPT7835/40/50/55/60/61) which simplifies up-
grades. The SPT7861 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 SPT7861 is available in 28-lead SOIC and 32-lead small
(7 mm square) TQFP packages over the commercial tem-
perature range. For availability of extended temperatureranges,
consult the factory.
