U-160 Simple Circuit Modifications Enhance Optocoupler

A goal of this application note is to illustrate the importance of the phase limitations that optocouplers have in power supply feedback loops. To this end other circuit topologies will be presented to

Designing Linear Amplifiers Using the IL300 Optocoupler

This servo operation linearizes the LED''s output flux and eliminates the LED''s time and temperature dependancy. The galvanic isolation between the input and the output is provided by a second PIN

Designing Linear Amplifiers Using the IL300 Optocoupler

The output section of the amplifier is a voltage follower. The output voltage is equal to the voltage created by the output photocurrent times the photodiode load resistor, R2.

Optocoupler Tutorial for Beginners

These optocouplers are designed for high-power applications. In these devices, the light from the LED triggers a photo-SCR, which then switches the output circuit on or off.
