If temperature drift needs to be calibrated after soldering externally, then together with the internal calibration we have a double drift calibration, which can easily work against each other.

    it is not recommended to apply an external temperature compensation, being the device already internally compensated over temperature. What it is suggested, in case of requirement of high accuracy, is to perform external calibration post-solder but at room temperature only (so not compensation at different temperatures)
