39 CMPLP - Low-Power Comparator Module

The Low-Power Comparator module is designed to work in applications where current consumption is a critical factor. Comparators are used to interface analog circuits to a digital circuit by comparing two analog voltages and providing a digital indication of their relative magnitudes. Comparators are very useful mixed signal building blocks because they provide analog functionality independent of program execution.

The low-power comparator includes the following features:

• Programmable input selection
• Programmable output polarity
• Rising/falling output edge interrupts
• Selectable common-mode input voltage ranges
• Wake-up from Sleep
• ADC auto-trigger
