An input phototransistor provides the servomechanism used to generate a feedback control signal for the input LED drive current thus compensating for the LED's nonlinear time and temperature characteristics. The output phototransistor provides an isolated signal that is linear with respect to the servo LED current. LOC117 features include wide bandwidth, high input-to-output isolation, and excellent servo linearity.
