DESCRIPTION  
iC-PT3313 is an optical sensor IC with integrated analog operation the amplified signal voltages are  
photosensors whose signals are converted into volt- available at the outputs, easing setting-up operation  
ages by low-noise transimpedance amplifiers. Pre- and optical alignment procedures.  
cise voltage comparators with hysteresis are used to  
generate the digital signals, supplied to the output Typical applications of iC-PT devices are incremental
