Features and Applications

The LOC111PTR is a Single channel Linear Optocoupler features an infrared LED optically coupled with two phototransistors.

The One feedback (input) phototransistor is used to generate a control signal that provides a servomechanism to the LED drive current. The other (output) phototransistor provides an output signal that is linear with respect to the servo LED current. The product features wide bandwidth, high input to output isolation and excellent servo linearity.
