Grounding

Use ground and power planes where possible. Ground and

power planes reduce the resistance and inductance of the power

planes and ground returns. The returns for the input, output

terminations, bypass capacitors, and RG should all 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.
