Feature Description (continued)

•

T is the unknown temperature in degrees Kelvin

•

To is a reference temperature in degrees Kelvin

(1)

By calibrating the output to read correctly at one temperature the output at all temperatures is correct. Nominally

the output is calibrated at 10 mV/K.

Calibrate for 2.982V at 25°C

7.4 Device Functional Modes

The LM135 has two functional modes calibrated and uncalibrated. For optimum accuracy, a one point calibration

is recommended. For more information on calibration, see Temperature Calibration Using ADJ Pin.
