Circuit Schematic Linear DC Signal Opto Isolator using LM358 IC

Sensor. - Here is Circuit Schematic Linear DC Signal Opto Isolator using LM358 IC like in figure 1 below. 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. Both the input and output circuits operate from single power supplies (one for the input side and a 2nd for the output side). Prior art generally requires both positive and negative power supplies –elimination of the negative power supplies simplifies the circuit.
