83 / 104 page  DocID018576 Rev 9 83/104 STM8S003F3 STM8S003K3 Electrical characteristics 87 1. Data based on characterization results. 2. ADC accuracy vs. negative injection current: Injecting negative current on any of the analog input pins should be avoided as this significantly reduces the accuracy of the conversion being performed on another analog input. It is recommended to add a Schottky diode (pin to ground) to standard analog pins which may potentially inject negative current. Any positive injection current within the limits specified for IINJ(PIN) and ΣIINJ(PIN) in Section 9.3.6 does not affect the ADC accuracy. Table 47.
