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.
