Yeah agreed, managed to track this down though app note AN4899 which states on page 18:"A GPIO is five-volt tolerant only if there is no analog function enabled on pin (for I/O structure FT_a, FT_fa, TT_a). If some analog input function is enabled on...

For the STM32L072 micro series what is the max input voltage on the ADC, without damaging the MCU? From the datasheet the pin should be VDD+4V tolerant as the I/O structure is FT. Is that still the same when the pin is configured as an ADC input?
