GENERAL DESCRIPTION

The SPT7835 is a 10-bit monolithic, low-cost, ultralow power analog-to-digital converter capable of minimum word rates of 5 MSPS. The on-chip track-and-hold function assures very good dynamic performance without the need for external components. The input drive requirements are minimized due to the SPT7835’s low input capacitance of only 5 pF.

Power dissipation is extremely low at only 75 mW typical at 5 MSPS with a power supply of +5.0 V. The digital outputs are +3 V or +5 V, and are user selectable. The SPT7835 is pin-compatible with an entire family of 10-bit, CMOS converters (SPT7835/40/50/55/60/61), which simplifies upgrades. The SPT7835 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. Output data format is straight binary.
