tional factor in resolution is the comparator’s stability in
its linear region. Many high-speed comparators are
useless in their linear region because they oscillate.
This makes the differential input voltage region around
zero unusable. Hysteresis helps to cure the problem
but reduces resolution (Figure 2). The devices do not
oscillate in the linear region and require no hysteresis,
which greatly enhances their resolution.
These products operate over a supply voltage range of
4.5V to 5.5V. Bypass V
mount ceramic capacitor. Mount the ceramic capacitor
as close as possible to the supply pin to minimize lead
inductance.
As with all high-speed components, careful attention to
board layout is essential for best performance. Use a
PC board with an unbroken ground plane. Pay close
attention to the bandwidth of bypass components and
place them as close as possible to the device.

Minimize the trace length and area at the comparator
inputs. If the source impedance is high, take the utmost
care in minimizing its susceptibility to pickup of unwant-
ed signals.
Most high-speed comparators have a minimum input
slew-rate requirement. If the input signal does not
transverse the region of instability within a propagation
delay of the comparator, the output can oscillate. This
makes many high-speed comparators unsuitable for
processing either slow-moving signals or fast-moving
signals with low overdrive. The design of these devices
eliminates the minimum input slew-rate requirement.
They are excellent for circuits from DC up to 200MHz,
even with very low overdrive, where small signals need
to be resolved.
