Applications
* for the LM135 include almost any type of temperature sensing over a
* 55˚C to +150˚C temperature range. The low impedance and linear output make interfacing to readout or control circuitry especially easy. The LM135 operates over a
* 55˚C to +150˚C temperature range while the LM235 ope
