GENERAL DESCRIPTION

The SPT7868 is a 10-bit, 80 MSPS analog-to-digital con-

verter with low power dissipation at only 627 mW typical at

80 MSPS with a power supply of +5.0 V. The digital outputs

are +3 V or +5 V, and are user selectable. The SPT7868

has incorporated proprietary circuit design and CMOS

processing technologies to achieve its advanced perfor-

mance. Inputs and outputs are TTL/CMOS compatible to

interface with TTL/CMOS logic systems. Output data for-

mat is straight binary.

The SPT7868 is available in a 28-lead SSOP package

over the industrial temperature range.
