(1) Data based on characterization results, not tested in production.

(2) All power (VDD) and ground (VSS) pins must always be connected to the external supply.

(3) IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum

cannot be respected, the injection current must be limited externally to the IINJ(PIN) value. A positive

injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS. For true open-drain

pads, there is no positive injection current, and the corresponding VIN maximum must always be respected

(4) 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 the I/O port pin characteristics section does not affect the ADC accuracy.

(5) When several inputs are submitted to a current injection, the maximum ΣIINJ(PIN) is the absolute sum

of the positive and negative injected currents (instantaneous values). These results are based on

characterization with ΣIINJ(PIN) maximum current injection on four I/O port pins of the device.
