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.
