General Description
The epc13x family products are monolithic, integrated high sensi-
tive photo-diode amplifiers for light-barrier, light-curtain, and the
like applications. It amplifies current pulses from reverse-biased
PIN photodiodes (e.g. BP104 by OSRAM) and discriminates the
amplified input light pulse before driving the open-drain output
stage. The device is controlled by an internal digital controller,
which uses no external clock signal. The power supply of the
device can be connected in anti-polar mode to decrease the wiring
effort in matrix operated light-curtain products. The device has
been optimized to utilize the least count of external components.
This device allows the design of short to long range light barriers
from a few millimeters up to tens of meters.
epc130/epc131 are the same devices but with an analog output.
Please refer to the corresponding data sheet epc130/epc131.
