PRINTED CIRCUIT LAYOUT
Generally, a good high frequency layout will keep power supply and ground traces away from the 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). If digital control lines must cross
analog signal lines (particularly inputs) it is best if they cross perpendicularly. TI suggests the following evaluation
boards as a guide for high frequency layout and as an aid in device testing and characterization:
