6.2 Absolute maximum ratings
Stresses above the absolute maximum ratings listed in Table 11: Voltage characteristics ,
Table 12: Current characteristics , and Table 13: Thermal characteristics may cause
permanent damage to the device. These are stress ratings only and functional operation of
the device at these conditions is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.

1. All main power (V

) and ground (V
SS
, V
SSA
) pins must always be connected to the external power supply, in the
permitted range.
2. This current consumption must be correctly distributed over all I/Os and control pins. The total output current must not be
sunk/sourced between two consecutive power supply pins referring to high pin count LQFP packages.
3. Negative injection disturbs the analog performance of the device. See note in Section 6.3.17 .
