GENERAL DESCRIPTION
The SPT7840 is a 10-bit monolithic, low-cost, ultralow-
power analog-to-digital converter capable of minimum
word rates of 10 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 SPT7840’s low input
capacitance of only 5 pF.
Power dissipation is extremely low at only 100 mW typical
(120 mW maximum) at 10 MSPS with a power supply of
+5.0 V. The digital outputs are +3 V or +5 V, and are user
selectable. The SPT7840 is pin-compatible with an entire
family of 10-bit, CMOS converters (SPT7835/40/50/55/60/
61), which simplifies upgrades. The SPT7840 has incorpo-
rated 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. Output data format is straight
binary.
The SPT7840 is available in a 28-lead SOIC package over
the industrial temperature range, and a 32-lead small
(7 mm square) TQFP package over the commercial
temperature range.
