supply pins, keeping leads short to minimize lead
inductance. For particularly noisy applications, use fer-
rite beads on the power-supply lines.
Board Layout
As with all high-speed components, careful attention to
layout is essential for best performance.
1) Use a printed circuit board with an unbroken
ground plane.
2) Pay close attention to the bandwidth of bypass
components and keep leads short.
3) Avoid sockets; solder the comparator and other
components directly to the board to minimize
unwanted parasitic inductance and capacitance.
Input S lew Rate
The MAX912/MAX913 design eliminates the input slew-
rate requirement imposed on many standard compara-
tors. As long as LE is high after the maximum propaga-
tion delay and the input is greater than the compara-
tor’s total DC error, the output will be valid without oscil-
lations.
Maximum Cloc k (LE) and S ignal Rate
The maximum clock and signal rate is 70MHz, based
on the comparator’s rise and fall time with a 5mV over-
drive at +25°C (Figure 1). With a 20mV overdrive, the
maximum propagation delay is 12ns and the clock and
signal rate is 85MHz.
