Grounding

Ground and power planes should be used where possible.

Ground and power planes reduce the resistance and inductance

of the power planes and ground returns. The returns for the

be kept as close to the ADA4899-1 as possible. The output load

ground and the bypass capacitor grounds should be returned to

the same point on the ground plane to minimize parasitic trace

inductance, ringing, and overshoot and to improve distortion

performance.

The ADA4899-1 packages feature an exposed paddle. For

optimum electrical and thermal performance, solder this

paddle to ground. For more information on high-speed circuit

design, see A Practical Guide to High-Speed Printed-Circuit-

Board Layout.
