GENERAL DESCRIPTION
The SPT7855 is a 10-bit monolithic, low cost, ultralow power
analog-to-digital converter capable of minimum word rates
of 25 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 SPT7855's low input capacitance of only
5 pF.
Power dissipation is extremely low at only 135 mW typical at
25 MSPS with a power supply of +5.0 V. The digital outputs
are +3 V or +5 V, and are user selectable. The SPT7855 is
pin-compatible with the entire family of SPT 10-bit, CMOS
converters (SPT7835/40/50/55/60/61) which simplifies
upgrades.The SPT7855 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 SPT7855 is available in 28-lead PDIP, 28-lead SOIC
and 32-lead small (7 mm square) TQFP packages over the
commercial and industrial temperature ranges.
