epc130/epc131
Photo-receiver Amplifier
General Description
Features
The epc13x family products are monolithic, integrated high sensi-  Low current consumption
tive photo-diode amplifiers for light-barrier, light-curtain, and the  High sensitivity
like applications. It amplifies current pulses from reverse-biased  Analog output
PIN photodiodes (e.g. epc300) and generates an analog output  CSP6 package with very small footprint and standard QFN16 pack -
signal, driven by a push-pull output stage. This device allows the
age available
design of short to long range light barriers from a few millimeters
up to tens of meters.
Applications
The analog output can be analyzed by signal processing circuitry
in oder to extract weak optical signals on a heavy noise floor. _{ Light barriers ranging from millimeters to tens of meters}
Thus, very sensitive light barriers or other optical sensors can be _{ Light curtains}
built with very limited effort.
 Smoke detectors
 Liquid detectors
The epc13x is controlled by a digital controller, which uses no ex- _{ Heart beat monitors}
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.
