Layout Considerations
General layout and supply bypassing play major roles in
high-frequency performance. Fairchild evaluation boards
help guide high-frequency layout and aid in device testing
and characterization. Follow the steps below as a basis
for high-frequency layout:
Include 6.8 μF and 0.01 μF ceramic capacitors.
Place the 6.8 μF capacitor within 0.75 inches of the
power pin.
Place the 0.01 μF capacitor within 0.1 inches of the
power pin.
Remove the ground plane under and around the part,
especially near the input and output pins, to reduce
parasitic capacitance.
Minimize all trace lengths to reduce series inductances.
Refer to the evaluation board layouts shown in Figure 24-
Figure 26 for more information.
When evaluating only one channel, complete the
following on the unused channel:
Ground the non-inverting input.
Short the output to the inverting input.
