I am trying to measure the temperature inside the IC where the N-factor is about 1.03.
IC have NPN Diode-Connected Configuration.
The distance between IC and TMP464 is close. (<30mm)
If 1.03 (0xD0) is written in register ”Remote temp N-factor correction” of TMP464, a temperature lower than the outside temperature is read.
- Outside Temp : 39.1C / Read value : 31.3C
However, If no correction (0x00) is made, the value close to the ambient temperature can be read.
- Outside Temp : 39.1C / Read value : 39.5C
The change in Read value before and after the correction is close to that of Terr, so the i2c writing is performed correctly.
Should I use offset correction? How should I determine the value?
