PRINTED CIRCUIT BOARD LAYOUT AND COMPONENT VALUES SECTION
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). Texas Instruments suggests the
following evaluation boards as a guide for high frequency layout and as an aid in device testing and
characterization:

Another important parameter in working with high speed/high performance amplifiers, is the component values
selection. Choosing external resistors that are large in value will effect 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 to a large extent. On the other hand, choosing very low value resistors could
load down nodes and will contribute to higher overall power dissipation.
