(1) Hysteresis on the comparator inputs is achieved with a Schmidt trigger configuration. This results in an effective 100-kΩ feedback
resistance between the output of the comparator and the non-inverting input of the comparator. There is an option to disable the
hysteresis and, with it, the feedback resistance; see the TMS320x2802x, 2803x Piccolo Analog-to-Digital Converter (ADC) and
Comparator Reference Guide (literature number SPRUGE5 ) for more information on this option if needed in your system.
