Optical comparator
Optek electronics
Each OPR5011 device is a hybrid sensor array that consists of three channels of the OPTEK OPC8332 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.
Features:
- Precise active area location
- Surface mountable
- TTL compatible output
- Wide supply voltage range
- Wide operating temperature range
Applications:
- High-speed applications
- High-resolution applications
- Applications requiring a wide range of light levels
