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 approxi-
mately an equal amount of infrared light. The
diodes produce a proportional amount of pho-
tocurrents. The ratio of the photocurrents stays
constant with high accuracy when either the
LED current changes or the ambient tempera-
ture changes. Thus one can control the output
diode current optically by controlling the input
photodiode current.
The IL350/1/8/9 optocouplers can be used
with the aid of operational ampli鏗乪rs in closed
loop conditions to achieve highly linear and
electrically isolated AC and or DC signal
ampli鏗乪rs.
