High-Speed Window Comparator
A window comparator circuit is used to determine when a signal is between two voltages. The TLV3501-Q1 can
readily be used to create a high-speed window comparator. V
HI
is the upper voltage threshold, and V
LO
is the
lower voltage threshold. When V
IN
is between these two thresholds, the output in Figure 19 is high. Figure 20
shows a simple means of obtaining an active low output. Note that the reference levels are connected differently
between Figure 19 and Figure 20. The operating voltage range of either circuit is 2.7 V to 5.5 V.
