Description
The OPL583 contains a monolithic integrated circuit which incorporates two independent photodiodes, linear amplifiers, Schmitt trigger circuits, and output transistors served by a common voltage regulator. The outputs are TTL/LSTTL compatible and can drive 8 TTL loads over a voltage range from 4.5 to 16 V. Applications include linear and rotary encoders with resolutions determined by external apertures. The fixed relative position of the two photodiodes and the matched characteristics of the two channels allow considerable design flexibility.

Features
• Two matched detectors with photolithographic control of relative position
• Dual Photologic® circuitry in single package provides reduced component count
• Open collector inverter output for flexibility of circuit interface
• Low cost plastic housing
