The comparator subsystem is built around a number of modules. Each subsystem contains two comparators, two reference 12-bit DACs, and two digital filters. Comparators are denoted "H" or "L" within each module where “H” and “L” represent high and low, respectively. Each comparator generates a digital output which indicates whether the voltage on the positive input is greater than the voltage on the negative input. The positive input of the comparator is driven from external pins.
Each comparator output passes through a programmable digital filter that can remove spurious trip signals. An unfiltered output is also available if filtering is not required. The negative input for only COMPH(CMPSSA) can be driven by an external pin or by programmable 12-bit DAC. The negative input for COMPL (CMPSSA) can only be driven by 12-bit DAC. The negative input for CMPSSB (COMPH and COMPL) can only be driven by the programmable 12-bit DAC.
