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
input, output terminations, bypass capacitors, and R
G
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

Board Layout
