    Hello,

    I have been asked to design a circuit which measures temperature using 3 lead RTD sensor of the type pt100,Ni 100,Ni120 & Cu10.
    I am not new to RTD.I have designed a board earlier which measures temperature using 2 lead RTD of the type pt100.

    I want to design a single circuit which applies to all the input types-pt100,Ni 100,Ni120 & Cu10.

    Please help.

    Regards,
    Mayuri

    The XTR105, by Texas Instruments, will do this all in one chip (plus a few R's and C's).
