The purpose in both cases is the same, i.e., to stabilize the operation of unused operational amplifiers and comparators and not to exert an influence on other operational amplifiers and comparators (within the same package).
There are differences between the stabilization methods. A voltage follower configuration that enables stabilization using negative feedback is recommended for operational amplifiers, while fixing the input voltage in order to achieve output stabilization is recommended for comparators.
- Operational amplifier:In a device with multiple channels, how should I handle the operational amplifiers not being used?
- Comparator: My device has multiple comparator channels; how should I handle comparators that are not being used?
