    the supply is coming from a transformer of +15V
    ckt is useful for thermocouple...
    Vref+ is positive analog voltage of ADC
    OPAMP is used in power supply ckt...and it has an input going to the non invrting terminal from this ckt
    Just help me analyse what will the flow of circuit be...
    why is a zener used in etc etc... Designed.PNG

    Your schematic is difficult to read. There is not much difference between crossed wires and intersected wires.

    What is R47 connected to?

    one end is connected to +15v supply coming from transformer and the other end is connected to emitter of a PNP transistor...
