Photologic® Sensors
Types OPL530, OPL530-OC, OPL531, OPL531-OC
Features
Four output options
High noise immunity
Direct TTL/LSTTL CMOS interface
Low cost plastic side-looking package
Mechanically and spectrally matched
to the OP140 and OP240 series LED's
Data rates to 250 kBaud
Low power consumption
Description
The OPL530, OPL530-OC, OPL531,
OPL531-OC contain a monolithic
integrated circuit which incorporates a
photodiode, amplifier, voltage regulator,
Schmitt trigger and an NPN output
transistor on a single silicon chip.
The OPL530 and OPL531 includes a 10
Kpull-up resistor (RL) from output to
VCC. The OPL530-OC and OPL531-OC
have an open-collector output.
These devices exhibit very stable
performance over supply voltages
ranging from 4.5 V to 16 V and a wide
range of irradiance levels.
The Photologic® chip is encapsulated in
a molded plastic package which has an
integral lens for enhanced optical
coupling and minimal optical spacing.

Notes:
(1) Derate linearly 2.67 mW/o C above 70o C.
(2) RMA flux is recommended. Duration can be extended to 10 sec. maximum when flow
soldering. Max 20 grams force may be applied to the leads when soldering.
(3) Irradiance measurements are made with λi = 935 nm.
(4) OC versions only. For ICC on pull-up versions add VCC/10 k.
