Table 33.
1. 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
V
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.
