8 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
To insure good sensing accuracy, several precautions must be taken. Like any temperature-sensing device, self-
heating can reduce accuracy. The LM135 should be operated at the lowest current suitable for the application.
Sufficient current, of course, must be available to drive both the sensor and the calibration pot at the maximum
operating temperature as well as any external loads.
If the sensor is used in an ambient where the thermal resistance is constant, self-heating errors can be calibrated
out. This is possible if the device is run with a temperature-stable current. Heating will then be proportional to
zener voltage and therefore temperature. This makes the self-heating error proportional to absolute temperature
the same as scale factor errors.

8.2.2 Detailed Design Procedure
For optimum accuracy, R1 is picked such that 1 mA flows through the sensor. Additional error can be introduced
by varying load currents or varying supply voltage. The influence of these currents on the minimum and
maximum reverse current flowing through the LM135 should be calculated and be maintained in the range of 0.4
mA to 5 mA. Minimizing the current variation through the LM135 will provide for the best accuracy. The
Operating Output Voltage Change with Current specification can be used to calculate the additional error which
could be up to 1 K maximum from the LM135A, for example.
