Description
The LOC117 Linear Optocoupler features
0.887-1.072
3750
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.
