The S7136 is a light modulation photo IC for optical synchronous detection under background light, integrating a photodiode, amplifier, comparator, oscillator, LED driver, and signal processor on a single chip. It supports 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 low hysteresis. Operates from 4.5 to 16 V supply, with output current up to 50 mA. Operating temperature range is -25 to +60 °C. Encased in a surface-mount package measuring 7.5 mm × 5.0 mm × 2.0 mm with a 0.4 × 0.4 mm photosensitive area. Cathode is open-collector driven. Soldering peaks at 230 °C for less than 5 seconds, with lead roots kept at least 1 mm from the body.
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. (S7136).
