    hello,
    It is an voltage follower Op Amp...
    I need to get under 5V for the V.out and also under 10mA for the I.out

    What i have is a 10k thermistor and i need to know what the value of the other resistor should be, and what it looks like drawn up

    take a look at the pic i attached

    I might be very wrong. Iout is only determined by the op-amp ,nothing with R1.
    To determine the Vout range, you need find out the temperature test range, then work out the maximum and minum resistance value of the thermister.
