Light modulation photo IC
S4282-51, S6809, S6846, S6986, S7136/-10, S10053
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) and a minimum
detection level of 0.2 μW/mm² typ. (S6809, S6846, S7136/-10).

Note: Exceeding the absolute maximum ratings even momentarily may cause a drop in product quality. Always be sure to use the
product within the absolute maximum ratings.
