Application Notes
(Continued)
Figure 6 shows the MUX output when selecting between a
1MHz sine and a 250KHz triangular waveform.
As can be seen in Figure 6 the output is well behaved and
there are no spikes or glitches due to the switching. Switch-
ing times are approximately around 500ns based on the time
when the output is considered “valid”.
Printed Circuit Board Layout, Component Values Selec-
tion, and Evaluation Boards:
Generally, a good high-frequency layout will keep power
supply and ground traces away from the inverting input and
output pins. Parasitic capacitances on these nodes to
ground will cause frequency response peaking and possible
circuit oscillations (see Application Note OA-15 for more
information).
Another
important
parameter
speed/high performance amplifiers, is the component values
selection. Choosing large valued external resistors, will ef-
fect the closed loop behavior of the stage because of the
interaction of these resistors with parasitic capacitances.
These capacitors could be inherent to the device or a
by-product of the board layout and component placement.
Either way, keeping the resistor values lower, will diminish
this interaction. On the other hand, choosing very low value
resistors could load down nodes and will contribute to higher
overall power dissipation.
National Semiconductor suggests the following evaluation
boards as a guide for high frequency layout and as an aid in
device testing and characterization:
