    I need a simple circuit to detect 5 to 12V dc voltage.

    How about a 12V mini lightbulb ?

    What sort of circuit do you need? Really, a small lamp is a good voltage detector.

    We just need more information. Do you need a high impedance load then? Do you need to actually be able to measure 5-12V? Do you need a 1MHz bandwidth? We need more information to help!!
