Information for application.

There is a simple technique of the device calibration for improving precision of temperature

measurement (see typical application circuits).

Calibration of the device occurs in one spot as the IC output voltage is proportional to absolute

of output voltage on temperature are determined only by characteristic incline. Therefore bias

calibration at one temperature corrects errors in the whole temperature range. Output voltage of

calibrated or non calibrated circuit may be derived from the following equation:

To

T

;

where Т – unknown temperature;

To ensure measurement precision they apply some rules. Degradation of the precision when
