Generally, a good high frequency layout keeps power supply and ground traces away from the inverting input and output pins. Parasitic capacitance on these nodes to ground cause frequency-response peaking and possible circuit oscillations (see the OA-15 Frequent Faux Pas in Applying Wideband Current Feedback Amplifiers application report 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:
