PRINTED CIRCUIT BOARD LAYOUT and EVALUATION BOARDS

Generally, a good high-frequency layout will keep power supply and ground traces away from the inverting input

and output pins. Parasitic capacitance on these nodes to ground will cause frequency response peaking and

possible circuit oscillations (see Application Note OA-15 (SNOA367) 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:
