Description

Hamamatsu S4289-61 Asynchronous type light modulation photo IC

The S4289-61 is an asynchronous type light modulation photo IC designed for reliable detection even under disturbance background light. A photodiode, preamplifier, comparator, oscillator and signal processing circuit, etc. are all integrated on a monolithic photo IC chip. Using asynchronous optical detection means that no wiring to a signal light source (such as LED) is required and allows greater versatility in equipment

Features
-Asynchronous detection
-Large allowable background illuminance: 4000 lx Typ.
-Minimum detection level: 0.2 uW/mm² Typ.
-Digital output (Output appears “L” by light input.).
-Small plastic package
