Has anyone face this issue that Pin no. 6 of OP07C shows garbage voltage sometimes. This voltage goes to ADC pin of microcontroller. Controller act on the base OP07C output. this garbage value affects the whole system functioning,

    Hello Vikas,

    • Do you have any scope captures of the OP07C garbage voltage you mention?
    • Is the OP07C output garbage present when the amplifier output is observed without the ADC connected to it?
    • Are you sure the garbage isn't coming out of the microcontroller ADC input pin?
    • Can you share your schematic showing the OP07C and microcontroller circuitry?
