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 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
