DESCRIPTION
The IL350/1/8/9 family of Linear Optocoupler  consist of an IRLED optically coupled to two  photodiodes. The emitter mechanically faces  both diodes enabling them to receive approximately an equal amount of infrared light. The  diodes produce a proportional amount of photocurrents. The ratio of the photocurrents stays  constant with high accuracy when either the  LED current changes or the ambient temperature changes. Thus one can control the output  diode current optically by controlling the input  photodiode current.
