Figure 4: Overdrive Recovery

Driving Capacitive Loads

The Frequency Response vs. CL plot on page 4,

illustrates the response of the KM4110 and KM4120. A

small series resistance (Rs) at the output of the amplifier,

illustrated in Figure 5, will improve stability and

settling performance. Rs values in the Frequency

Response vs. CL plot were chosen to achieve maximum

bandwidth with less than 1dB of peaking. For maximum

flatness, use a larger Rs.

a capacitive load

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:

s

Include 6.8

µF and 0.01µF ceramic capacitors

s

Place the 6.8

µF capacitor within 0.75 inches

of the power pin

s

Place the 0.01

µF capacitor within 0.1 inches

of the power pin

s

Remove the ground plane under and around the

part, especially near the input and output pins to

reduce parasitic capacitance

s

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 evaluation board is built for dual supply

operation. Follow these steps to use the board in a

single supply application:

1. Short -Vs to ground

2. Use C3 and C4, if the -Vs pin of the KM4110 or

KM4120

is

not

directly

connected

to

the

ground plane.
