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. epc300) and generates an analog output
signal, driven by a push-pull output stage. This device allows the
design of short to long range light barriers from a few millimeters
up to tens of meters.
The analog output can be analyzed by signal processing circuitry
in oder to extract weak optical signals on a heavy noise floor.
Thus, very sensitive light barriers or other optical sensors can be
built with very limited effort.
The epc13x is controlled by a digital controller, which uses no ex-
ternal clock signal. The device has been optimized to utilize the
least count of external components.
epc134-epc139 are the same devices but with an digital output.
