Light modulation photo IC

Fewer detection errors even under disturbance background light

S4282-51, S6809, S6846, S6986, S7136/-10, S10053

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,
