The Maximum Supply Current That Wasn't | Analog Devices
Figure 6. If V OUT is driven high by Q5/Q3/Q4, the supply current will be a function of the values of R4 and R6. These values are selected to maximize the op amp performance and minimize die area, not comparator operation. When V OUT is driven low by Q6/R1/Q1, the supply current will be determined by R1. Again, the values of R1, I1, etc. are chosen for op amp performance, not comparator ...
