Hi,

I've tried to set the correct offset for a thermal diode sensor and came accross the EE-346.

On page 5 is the formula for the measurment error and an example are shown but the 2 formulas do not match.

Equation 2: divided by (273,15Kelvin + T)

Equation 3: multiplied with (273,15Kelvin + T)

See also picture attached.

Which one is correct?

Thanks!

Christian

Hi Christian,

The equation 2 mentioned in the Application Note EE-346 on Page 5 is wrong.

The equation 3 used is correct.

You can see the correct formula on page 14 of the ADM1032 datasheet . The link for the datasheet is given below:
