The LOC117 Linear Optocoupler features

an infrared LED optically coupled to a pair of

phototransistors. 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.
