TMS320F280023-Q1: Accuracy internal Temperature Sensor

Part Number: TMS320F280023-Q1

Hi Team, 

what is the absolute an relative measurement uncertainty of the internal temperature sensor. It is not written in the datasheet: 



  • Hi Jan,

    We explicitly do not spec. and absolute accuracy of the temperature sensor because our test flow does not support robustly guaranteeing a min/max accuracy.  The +/-15 deg. C is a conservative estimate based on characterization, but is listed as typical for the previously mentioned reasons.  Note that accuracy will be better in the room to hot temp range and worst at cold-temp.  

    As far as relative accuracy, the linearity and repeatability of the sensor is actually very good; typically about +/-1 deg. C.
