Linear optocoupler
Pure resistor and non-polarity output
Wide range of analog linear resistance, "on" at the low resistance.
"off" at the high resistance.
Simple circuit configuration suitable for DC and AC use
Input to output isolation, and low distortion coupling
The LLI‑2203 is a linear optocoupler developed by Senba Sensing. The LLI‑2203 converts changes in input current into corresponding variations in resistance using an LED paired with a light‑sensitive element. The LLI‑2203 operates as a current‑input‑controlled, non‑polarized resistance output device. The LLI‑2203 is commonly used in light‑sensitive circuits, analog signal isolation, and applications requiring current‑to‑resistance conversion.
