1. Data based on characterisation results for LQFP80 device with VREF+/VREF-, not tested in production.
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 10.3.6 does not affect the ADC accuracy.
