SPT9687

DUAL ULTRAFAST VOLTAGE COMPARATOR

GENERAL DESCRIPTION

The SPT9687 is a dual, very high-speed monolithic com-

parator. It is pin compatible with, and has improved perfor-

mance over Analog Device's AD9687. The SPT9687 is

designed for use in Automatic Test Equipment (ATE), high-

speed instrumentation, and other high-speed comparator

applications.

Improvements over other sources include reduced power

consumption, reduced propagation delays, and higher input

impedance.

The SPT9687 is available in 16-lead SOIC, 16-lead plastic

DIP, 20-lead PLCC and 20-contact LCC packages over the

industrial temperature range. It is also available in die form.
