Data guaranteed by design, not tested in production.
2.
The comparator accuracy depends on the environment. In particular, the following cases may reduce the accuracy of the
comparator and must be avoided:
- Negative injection current on the I/Os close to the comparator inputs
- Switching on I/Os close to the comparator inputs
- Negative injection current on not used comparator input.
- Switching with a high dV/dt on not used comparator input.
These phenomena are even more critical when a big external serial resistor is added on the inputs.
