Optical Comparator Array
• Precise active area location
• Surface mountable
• TTL compatible output
• Wide supply voltage range
• Wide operating temperature range
Each OPR5011 device is a hybrid sensor array that consists of three channels of the OPTEK differential optical comparator
(‘TRI-DOC”) IC. The single chip construction ensures very tight dimensional tolerances between active areas.
Specifically designed for high-speed/high-resolution encoder applications, the open collector output switches based on the
comparison of the input photodiode’s light current levels. Logarithmic amplification of the input signals facilitates operation
over a wide range of light levels.
The surface-mountable opaque polyimide package shields the photodiodes from stray light and can withstand multiple
exposures to the most demanding soldering conditions, while the gold-plated wraparound contacts provide exceptional
storage and wetting characteristics.
See Application Bulletin 237 for handling instructions.
• High-speed applications
• High-resolution applications
• Applications requiring a wide range of light levels
