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
K鈩?pull-up resistor (R
L
) from output to
V
CC
. 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
廬
chip is encapsulated in
a molded plastic package which has an
integral lens for enhanced optical
coupling and minimal optical spacing.
