The raw data for the embedded internal reference voltage is measured at 30°C +/-5°C. What is the VREFINT_CAL range when the same MCU is measured at ST at 25°C and at 35°C?

STM32L151xE
In the datasheet for the STM32L151 is missing the value of the sampling switch resistance R_ADC in table 55. Does anybody knows the R_ADC value?

Yes, I'm looking the internal resistance value of the MUX switch (R_ADC not R_AIN). But I also assume it is 6kOhm as in the datasheet of STM32F405.
