21. OPA/Comparator
SM59R16A5 had integrated an OPA/Comparator module on chip. This module supports OPA and Comparator
modes individually according to user’s configuration. When OPA Mode enabled, dual OP-Amps may be applied to
single or two-stage amplifier network, and may be applied as a front-end signal process and internally routed to
specific ADC channel. When Comparator Mode enabled, an internal reference voltage is available to be configured
on comparator terminals.
If OPA and Comparator Mode both are enabled at same module, the OPA Mode has higher priority.
The OPA/Comparator SFR show as below:
