    Hi,

    is there a breakdown voltage for the temeprature sensor LM335, i looked on the national semiconductor spec sheet and it doesnt say.

    thanks to anyone who can answer this for me!

    It is supposed to be driven with a current, like 1mA. Its voltage drop is a function of temperature, and is independent of current. How would its terminal voltage ever get out of bounds as long as the current is limited?

    As MikeML posted, the LM335 is a current device.

    However, keep in mind that current through the device will tend to increase it's temperature, which will make readings less accurate.

    See the datasheet for details.
