Dual Channel Photologic Encoder Detector
OPL583
Description:
OPL583 contains a monolithic integrated circuit that incorporates two independent photodiodes, two linear
amplifiers, two Schmitt trigger circuits and two output transistors which are all served by a common voltage
regulator. The fixed position of the two photodiodes and the matched characteristics of the two channels allow
considerable design flexibility. The outputs are TTL/LSTTL compatible and can drive up to 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.
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

Notes:
(1) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
(2) Derate linearly 0.37 V/°C above 58° C.
(3) Derate linearly 2.67 mW/° C above 25° C.
(4) A 0.01 µF capacitor should be used across the VCC and GND leads to stabilize the power supply line.
(5) Irradiance measurements are made with λ = 940 nm.
