Photo-receiver Amplifier

Features

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.


