Calculation of the Junction Temperature
The total power dissipation PTOT of the chip increases its temperature above the ambient temperature.
The power multiplied by the total thermal resistance RthJA (Junction to Ambient) leads to the final junction
temperature. RthJA is the sum of the addition of the values of the two components Junction to Case and Case to
Ambient.
(1)
Example (assuming no load on Vout):
(2)
For molded sensors, the calculation with RthJC is more appropriate.

Electrical Parameters
The indicated electrical parameters apply to the full operating range, unless otherwise specified. The typical values
correspond to a supply voltage VDD = 5.0 V and 25 °C, unless individually specified. All other values correspond
to -40 °C < TJ < 150°C.
