Linear Optocouplers and Isolation Amplifiers
OptoMOS™ Linear Optocouplers feature an infrared LED
optically coupled to a pair of phototransistors. One feedback
(input) phototransistor is used to generate a control signal that
provides a servomechanism to the LED drive current thus
compensating for the LEDs nonlinear time and temperature
characteristics. The output phototransistor provides an isolated
output signal that is linear with respect to the servo LED current.
Features

OptoMOS™ Linear Isolation Amplifiers integrate a linear
optocoupler with two independent LF356 op-amps in a single
16-pin package. These amplifiers can couple both AC and DC
signals in either unipolar or bipolar modes, while providing
3750V
compensate for the nonlinear time and temperature
characteristics of the LED, these amplifiers distinguish
themselves among conventional optocouplers by significantly
improving linearity and stability.
Applications
