STM8S003 Analog input failure

Question asked by teoh.jason on Feb 11, 2015

Hi Sir,

We have a lot of failures on STM8S003 during MP, where an analogue input stops functioning properly (reading value of the ADC is incorrect). Since the datasheets are not so clear, do you know if there is any constraints on the impedance matching of a low impedance source to the STM8S003 analog input?
