S4289-61, Light modulation photo IC

Light modulation photo IC S4289-61 Asynchronous type light modulation photo IC The S4289-61 is an asynchronous type light modulation photo IC designed for reliable detection even under disturbance background light.

A photodiode, preampliﬁer, comparator, oscillator and signal processing circuit, etc.

are all integrated on a monolithic photo IC chip.

Using asynchronous optical detection means that no wiring to a signal light source (such as LED) is required and allows greater versatility in equi
