Newbie: current ADC ?

  1. Hi People,

    Does something like a current ADC exist ? I want to digitally measure the
    current through a wire without introducing a resistor and measuring a
    voltage drop etc..

    Does anyone know of a reasonably simple-to-use IC that does current to
    digital conversions.

    Many thanks and a happy Christmas,

    Doug

    If you don't want to break the wire, a current transformer (CT) is the
    common way of measuring AC current with causing any affect on the current
    being measured.

    A clamp (or hall effect) current sensor converts the currnent flowing through
    any conductor placed inside it's ring/jaws into a small voltage than can be
    measured.
    no. but a clamp sensor (etc) can be connected to a regular ADC (or any other
    voltage measuring aparatus)

    Bye.
