DESCRIPTION
The IL350/351/358/359 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.
The IL350/351/358/359 optocouplers can be used with the
aid of operational amplifiers in closed loop conditions to
achieve highly linear and electrically isolated AC and or DC
signal amplifiers.
