SPT9687

SPT9687 DUAL ULTRAFAST VOLTAGE COMPARATOR FEATURES Propagation Delay <2.3 ns Propagation Delay Skew <300 ps Low Power: 185 mW Low Offset ±3 mV Low Feedthrough and Crosstalk Differential Latch Control APPLICATIONS High-Speed Instrumentation, ATE High-Speed Timing Window Comparators Line Receivers A/D Conversion Threshold Detection GENERAL DESCRIPTION The SPT9687 is a dual, very high-speed monolithic comparator. It is pin compatible with, and has improved performance over Analog Device's AD9687. The SPT9687 is designed for use in Automatic Test Equipment (ATE), highspeed 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.
