TMP20: Temperature-solved equation error ?

Hi,

I am using a TMP20 sensor in my design and when implementing the equation solved for temperature found in datasheet page 7:

The result is way off.

However I believe the LM20 is similar and in LM20 datasheet page 9 under Table 1 we can see:

And with this formula, the result is good and match with the 1863.9mV@0°C and 1574mV@25°C given in the TMP20 datasheet.

So is the formula in TMP20 datasheet wrong ?

Also it seems there is an extra "2" in the TMP20 datasheet: 2.19262 vs 2.1962 for LM20 ?

Could you please confirm the formula ?

Thank you and best regards
