Depending on the SDADCx operation mode, there can be more constraints between
V
REFSD+
, V
DDSD12
and V
DDSD3
which are described in reference manual RM0313.

1. VDDSD12 is the external power supply for the PB2, PB10, and PE7 to PE15 I/O pins (the I/O pin ground is internally
connected to V
SS
). VDDSD3 is the external power supply for PB14 to PB15 and PD8 to PD15 I/O pins (the I/O pin ground
is internally connected to V
SS
). V
DD
(VDD_x) is the external power supply for all remaining I/O pins (the I/O pin ground is
internally connected to V
SS
).
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. Positive injection is not possible on these I/Os and does not occur for input voltages lower than the specified maximum
value.

disturbs the analog performance of the device. See note

below Tab le 62.
6. When several inputs are submitted to a current injection, the maximum ΣI
INJ(PIN)
is the absolute sum of the positive and
negative injected currents (instantaneous values).
