Light modulation photo IC


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 equipment
