GENERAL DESCRIPTION
The SPT7868 is a 10-bit, 80 MSPS analog-to-digital converter 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 performance. Inputs and outputs are TTL/CMOS compatible to interface with TTL/CMOS logic systems. Output data format is straight binary.
The SPT7868 is available in a 28-lead SSOP package over the industrial temperature range.
