This linear optocoupler is built with MOC5010 and can be used to isolate a circuit from main grid, audio interface, in medical electronics and many other applications. Because of its high isolation resistance (10 11 Ω), MOC5010 is used in applications where a circuit is powered directly from main power. With a bandwidth from 5 Hz to 100 kHz ...

Using the 4N25 for Audio. However it is also possible to use some of the much cheaper, general purpose phototransistor optocouplers for audio applications, such as the popular 4N25 illustrated in Fig. 5.3.2 also from Vishay, which is normally used for low frequency digital signals (in saturation mode) or DC applications (in linear mode) for limited audio applications.

The Applied Optocoupler In this audio frequency application, I have chosen the IL300 linear optocoupler, which consists of an IRLED that is irradiating an isolated feedback and an output PIN photodiode in a bifurcated arrangement. The feedback photodiode captures a percentage of the LED’s flux and generates a control signal that can be used ...

Linear optocoupler IL300 One of the diode is part of the output circuit, the other is used as feedback. IL300 optocoupler is suitable for both direct and transfer AC signal with a bandwidth of 200 kHz via a linearity of up to 0.01%. The function is stable in terms of temperature, while the temperature coefficient is only ± 0.05% / oC.

Linear opto isolator circuit. This is the linear opto isolator circuits that use a few parts and cheap. In circuit we use the opto compiler ICs number of MOC 5010 as a base. It can use it in many ways. For example, separate the circuit from the power line, send an audio signal, Electronic medical, etc.
Linear DC Signal Opto-Isolator / Optocoupler Circuit
https://www.electroschematics.com/linear-dc-signal-opto-isolator/
Linear DC Signal Opto Isolator. Jim Keith. This simple circuit provides better than 1% accuracy in optically coupling a DC voltage signal. To compensate for the non-linearity of the optical isolator, an identical device is connected in the feedback loop. To further enhance stability, both optical isolators are located inside the same IC.

On the output side of the optocoupler, a quiescent current is set up (by the optocoupler action) in the phototransistor, and causes a quiescent voltage to be set up across RV1, which should have its value adjusted to give a quiescent output value of half-supply voltage. The audio output signal appears across RV1 and is DC-decoupled via C2.
