Precision Temperature Sensors

perature range. The LM335 operates from −40°C to 100°C.

The LM135/LM235/LM335 are available packaged in hermet-

ic TO-46 transistor packages while the LM335 is also avail-

able in plastic TO-92 packages.

General Description

The LM135 series are precision, easily-calibrated, integrated

circuit temperature sensors. Operating as a 2-terminal zener,

the LM135 has a breakdown voltage directly proportional to

absolute temperature at +10 mV/°K. With less than 1Ω dy-

namic impedance the device operates over a current range

of 400 μA to 5 mA with virtually no change in performance.

When calibrated at 25°C the LM135 has typically less than 1°

C error over a 100°C temperature range. Unlike other sensors

the LM135 has a linear output.

Features

Directly calibrated in °Kelvin

■

1°C initial accuracy available

Operates from 400 μA to 5 mA

Less than 1Ω dynamic impedance

Easily calibrated

■

Applications for the LM135 include almost any type of tem-

perature 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.

Wide operating temperature range

200°C overrange

Low cost

The LM135 operates over a −55°C to 150°C temperature

range while the LM235 operates over a −40°C to 125°C tem-
