    Hi everybody,

    I have a question,
    What types of applications this circuit can be used for? This circuit is called "Multi-level voltage detector" ?

    A 741 opamp is 44 years old, is noisy and has a poor frequency response so it is not used to do much anymore. Much better opamps are available that cost the same or less, have low noise and have a much wider frequency response.

    Your circuit is a DC voltage comparator. It has a switch that changes the reference voltage from +6.67V in a few steps to +10V.
