  • Low cost plas tic hous ing De scrip tion 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. Ab so lute Maxi mum Rat ings (TA = 25o C un less oth er wise noted) Lead Sol der Tem pera ture [1/16 inch (1.6 mm) from case for 5 sec. with sol der ing iron] Notes: (1) Derate linearly 2.67 mW/o C above 25o C. (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 58o C. Sche matic Prod uct Bul le tin OPL583 August 1996 Dual Chan nel Pho tologic® En coder De tec tor Type OPL583 Op tek Tech nol ogy, Inc. 1215 W.
