Linear Optocoupler
Description
The LOC117 Single Linear Optocoupler features an
infrared LED optically coupled with two photodiodes.
One feedback (input) photodiode is used to generate
a control signal that provides a servomechanism
to the LED drive current, thus compensating
for the LED's nonlinear time and temperature
characteristics. The other (output) photodiode
provides an output signal that is linear with respect
to the servo LED current. The product features
wide bandwidth, high input to output isolation, and
excellent servo linearity.

Absolute Maximum Ratings are stress ratings. Stresses in
excess of these ratings can cause permanent damage to
the device. Functional operation of the device at conditions
beyond those indicated in the operational sections of this
data sheet is not implied.
Typical values are characteristic of the device at +25°C,
and are the result of engineering evaluations. They are
provided for information purposes only, and are not part of
the manufacturing testing requirements.
