Linear Optocoupler for Optical DAA

in Telecommunications, High Performance

DESCRIPTION

The IL350, IL358 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, IL358 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.
