corresponding V
Negative injection disturbs the analog performance of the device. In particular, it induces leakage currents throughout the
device including the analog inputs. To avoid undesirable effects on the analog functions, care must be taken:
- Analog input pins must have a negative injection less than 0.8 mA (assuming that the impedance of the analog voltage is
lower than the specified limits)
- Pure digital pins must have a negative injection less than 1.6mA. In addition, it is recommended to inject the current as
far as possible from the analog input pins.
No negative current injection allowed on PB0 and PB1 pins.
When several inputs are submitted to a current injection, the maximum ΣI
negative injected currents (instantaneous values). These results are based on characterization with ΣI
current injection on four I/O port pins of the device.
