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 iso-
lated AC and or DC signal amplifiers.
Description
The IL350/351/358/359 family of Linear Optocoupler
consist of an IRLED optically coupled to two photo-
diodes. The emitter mechanically faces both diodes
enabling them to receive approximately an equal
amount of infrared light. The diodes produce a pro-
portional 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 out-
put diode current optically by controlling the input
photodiode current.

Absolute Maximum Ratings
Tamb = 25 °C, unless otherwise specified
Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the device. Functional operation of the device is
not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
Maximum Rating for extended periods of the time can adversely affect reliability.
