DESCRIPTION
The iC-VP device is a photocurrent amplifier with downstream threshold switch and monolithic integrated
sensor diode. The device functions as a photoelectric detector, in light barriers for example.
The threshold is adjusted with an external resistor. After approx. 1
s delay a photocurrent of sufficient
size creates a low signal which is compatible with CMOS and LSTTL levels at the output.
The iC-VP can be utilized in a customized COB package as a multi-chip module for multi-channel
scanning absolute encoders.
TO18 metal can packages are available for single-channel light barrier applications.
