The S6809 is a light modulation photo IC designed for optical synchronous detection under disturbance from background light, integrating a photodiode, preamplifier, comparator, oscillator, LED driver, and signal processing circuit on a single chip. It features a minimum detection level of 0.2 µW/mm² typ. and an allowable background light level of 3000 lx typ., with a digital output and small hysteresis. The device operates from a 4.5 V to 16 V supply, with an output voltage low level of 0.4 V max. at 16 mA, and a high level of 4.5 V min. The package is an SMD type with dimensions of 5.2 mm × 5.0 mm × 2.5 mm, and it supports operating temperatures from -25 °C to +60 °C. The part is suited for applications such as optical switches and paper detection in office machines.
Fewer detection errors even under disturbance background light
This light modulation photo IC was 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 a minimum detection level of 0.2 uW/mm2 Typ.
