GENERAL DESCRIPTION

The SPT7850 is a 10-bit monolithic, low-cost, ultralow-

power analog-to-digital converter capable of minimum

word rates of 20 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 SPT7850’s low input

capacitance of only 5 pF.

Power dissipation is extremely low at only 140 mW typical

(165 mW maximum) at 20 MSPS with a power supply of

+5.0 V. The digital outputs are +3 V or +5 V, and are user

selectable. The SPT7850 is pin-compatible with an entire

family of 10-bit, CMOS converters (SPT7835/40/50/55/60/

61), which simplifies upgrades. The SPT7850 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 SPT7850 is available in 28-lead 300 mil PDIP and

32-lead small (7 mm square) TQFP packages over the

commercial temperature range, and in a 28-lead SOIC

package over the industrial temperature range.
