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?

TDK,

IMO DGian.1 is looking for the resistance of the MUX switch.

You are likely correct, as usual. Value is probably 6 kOhm as in other families but agreed it's not in the datasheet.

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.
