Light modulation photo IC S4282-51, S6809, S6846, S6986, S7136/-10, S10053/-01DT Fewer detection errors even under disturbance background light These light modulation photo ICs were developed for optical synchronous detection under disturbance background light. A photodiode, preamplifier, comparator, oscillator, LED driver and signal processing circuit, etc. are all integrated on a monolithic photo IC chip. Optical synchronous type photoreflectors and photointerrupters, which less susceptible to disturbance background light, can be easily configured by just connecting an external LED to this photo IC. Our unique circuit design achieves an allowable background light level of 10000 lx typ. (S4282-51, S6986, S10053/-01DT) and a minimum detection level of 0.2 µW/mm2 typ. (S6809, S6846, S7136/-10).
