I'm simulating the following comparator circuit using TINA-TI (Version 126.96.36.199 SF-TI). The behavior, however, is not as expected:
Hopefully it is clear that V- remains constant, while V+ swings above and below it. The output stays at 5V though, it only slightly nudges in the right direction.
As a reference, here's the comparator LPV7215 datasheet.
Common mode input voltage is within range, inputs are within range, power supply is within range. The output is a push-pull. What gives?
