Driving Capacitive Loads
The Frequency Response vs. C
L
plot on page 4,
illustrates the response of the KM4100 and KM4101. A
small series resistance (R
s
) at the output of the amplifier,
illustrated in Figure 5, will improve stability and
settling performance. R
s
values in the Frequency
Response vs. C
L
plot were chosen to achieve maximum
bandwidth with less than 1dB of peaking. For maximum
flatness, use a larger R
s
.

Layout Considerations
General layout and supply bypassing play major roles
in high frequency performance. Fairchild has evaluation
boards to use as a guide for high frequency layout
and to aid in device testing and characterization.
Follow the steps below as a basis for high frequency
layout:
I
Include 6.8
μ
F and 0.01
μ
F ceramic capacitors
I
Place the 6.8
μ
F capacitor within 0.75 inches
of the power pin
I
Place the 0.01
μ
F capacitor within 0.1 inches
of the power pin
I
Remove the ground plane under and around the
part, especially near the input and output pins to
reduce parasitic capacitance
I
Minimize all trace lengths to reduce
series inductances
Refer to the evaluation board layouts shown in Figure
7 for more information.
Evaluation Board Information
The following evaluation boards are available to aid
in the testing and layout of this device:
Evaluation board schematics and layouts are shown in
Figure 6 and Figure 7.
The KEB002 and KEB003 evaluation boards are built
for dual supply operation. Follow these steps to use
the board in a single supply application:
1. Short -V
s
to ground
2. Use C3 and C4, if the -V
s
pin of the KM4100 or
KM4101 is not directly connected to the
ground plane.
