Comparators With/Without Reference
Power-supply bypass capacitors are not typically
needed, but use 100nF bypass capacitors close to the
device’s supply pins when supply impedance is high,
supply leads are long, or excessive noise is expected
on the supply lines. Minimize signal trace lengths to
reduce stray capacitance. A ground plane and sur-
face-mount components are recommended. If the REF
pin is decoupled, use a new low-leakage capacitor.
Figure 5 shows a zero-crossing detector application.
The MAX9119’s inverting input is connected to ground,
and its noninverting input is connected to a 100mV
signal source. As the signal at the noninverting input
crosses 0V, the comparator’s output changes state.
The Typical Application Circuit shows an application
that converts 5V logic to 3V logic levels. The MAX9120
is powered by the +5V supply voltage, and the pullup
resistor for the MAX9120’s open-drain output is con-
nected to the +3V supply voltage. This configuration
allows the full 5V logic swing without creating overvolt-
age on the 3V logic inputs. For 3V to 5V logic-level
translations, simply connect the +3V supply voltage to

and the +5V supply voltage to the pullup resistor.
