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
