Figure 1. Damping the Reference Output
Figure 2. Damping Resistance vs Bypass Capacitor Value
Figure 3 shows the bypassed reference output with a
square wave applied to the V
+
pin. Resistors R2 and R3 set
10mV of hysteresis voltage band while R1 damps the
reference response. Note that the comparator output
doesn’t trip.
Low Voltage Operation: V
+
= 1.6V
The guaranteed minimum operating voltage is 2V (or
±
1V). As the total supply voltage is reduced below 2V, the
performance degrades and the supply current falls. At low
supply voltages, the comparator’s output drive is reduced
and the propagation delay increases. The V
REF
and V
OS
are
also slightly worse. The useful input voltage range extends
from the negative supply to 0.9V below the positive
supply. Test your prototype over the full
temperature and supply voltage range if operation below
2V is anticipated. Because of the increase in supply
current, operation below 1.5V is not recommended
(Figure 4).
