Optical Comparator Array
OPR5011
OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.
Description:
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 photodiodes 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.
Features:
" Precise active area location
" Surface mountable
" TTL compatible output
" Wide supply voltage range
Applications:
" High-speed applications
" High-resolution applications
" Applications requiring a wide
range of light levels
