Product Overview

The LOC110 Single Linear Optocoupler is designed for high-fidelity analog signal transmission, featuring an infrared LED optically coupled with two photodiodes. A feedback photodiode creates a control signal to stabilize the LED drive current, compensating for non-linearities. An output photodiode provides a signal linearly proportional to the servo LED current. This optocoupler offers wide bandwidth, high isolation, and excellent servo linearity, making it ideal for applications requiring precise analog signal coupling and isolation.
