Light receiving head amplifier PDIC for photoelectric switches

We developed a new PDIC(Photo Detector Integrated Circuit) , which performs voltage output as analog wave pattern only from AC component of receiving light signal. It simultaneously realized reduced current consumption and high sensitivity by our unique process technology, and due to the electromagnetic shield formed on the surface of detector, it enhanced resistance against the electromagnetic noise from peripheral devices. Most suitable for the use of light signal input unit of a photoelectric switch or various optical sensors.Best suitable for the use of light signal input part of a photoelectric switch or various optical sensors.

■ Characteristics
