Detailed Description
The MAX9647/MAX9648 are low-cost, general-purpose
comparators that have a single-supply +1.8V to +5V
operating voltage range. The common-mode input range
extends from -0.1V below the negative supply to within
+0.7V of the positive supply. They require approximately
60FA per comparator with a 5V supply and 52FA with a
2.7V supply.
The MAX9648 has 2mV of hysteresis for noise immunity.
This significantly reduces the chance of output oscilla-
tions even with slow moving input signals. The ICs are
ideal for automotive applications because they oper-
ate from -40NC to +125NC. See the Typical Operating
Applications Information
Hysteresis
Many comparators oscillate in the linear region of opera-
tion because of noise or undesired parasitic feedback.
This tends to occur when the voltage on one input is
equal or very close to the voltage on the other input. The
MAX9648 has internal hysteresis to counter parasitic
effects and noise.
The hysteresis in a comparator creates two trip points:
one for the rising input voltage and one for the falling
input voltage (Figure 1). The difference between the trip
points is the hysteresis. When the comparator’s input
voltages are equal, the hysteresis effectively causes
one comparator input to move quickly past the other,
thus taking the input out of the region where oscillation
occurs. This provides clean output transitions for noisy,
slow-moving input signals.
