DATA SHEET
3.4.1. Storage and Shelf Life
The permissible storage time (shelf life) of the sensors is unlimited, provided the sensors are stored at a maximum of
30 °C and a maximum of 85% relative humidity. At these conditions, no Dry Pack is required.
Solderability is guaranteed for one year from the date code on the package.
3.5. Recommended Operating Conditions
Functional operation of the device beyond those indicated in the “Recommended Operating Conditions/Characteris-
tics” is not implied and may result in unpredictable behavior of the device and may reduce reliability and lifetime.
All voltages listed are referenced to ground (GND).

3.5.1. Power Diagram
Due to the current source interface and the sensor’s power dissipation, it is not possible to use all current level and
supply voltage combinations over the full temperature range. Fig. 3–5 to Fig. 3–7 describe the possible ambient tem-
perature, supply voltage, and current level combinations for different thermal resistance values. To enable usage of
the sensor at high ambient temperatures, it is necessary to have a very good thermal coupling of the sensors and
the module. It is also necessary to select low values for the high current level.
