S4282-51 is a light modulation photo IC. 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 photo interrupters, 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. Typical applications are paper detection in office machine (copiers, fax machines etc.), optical switches.

• Large allowable background light level: 10000 lx typ
• Minimum detection level is 0.7uW/mm typ
• Digital output (output appears L by light input)
• Supply voltage range from 4.5 to 16V (Ta=25C, VCC=5V)
• Current consumption is 4mA typical (Vo, LED terminals open, Ta=25C, VCC=5V)
• Operating temperature range from -40 to 100C
• Frequency response is 1.25KHz typ (Ta=25C, VCC=5V)
