Dual Channel Photologic^® Encoder Detector
Type OPL583
Features
• Two matched detectors with photo-
lithographic control of relative position
• Dual Photologic^® circuitry in single
package provides reduced component
count
• Open collector inverter output for flexi-
bility of circuit interface
• Low cost plastic housing
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.

(2) RMA flux is recommended. Duration can be extended to 10 sec. max when flow soldering.
Max 20 grams force may be applied to leads when flow soldering.
(3) A 0.01 µF capacitor should be used across the VCC and GND leads to stabilize the power
supply line.
(4) Irradiance measurements are made with λ= 940 nm.
(5) Derate linearly 0.37 V/^o C above 58^o C.
