AD8003
Data Sheet
Rev. C | Page 14 of 16
Minimizing the trace length and widening the trace from the
capacitors to the amplifier reduces the trace inductance. A
series inductance with the parallel capacitance can form a tank
circuit, which can introduce high frequency ringing at the output.
This additional inductance can also contribute to increased
distortion due to high frequency compression at the output.
The use of vias should be minimized in the direct path to the
amplifier power supply pins because vias can introduce parasitic
inductance, which can lead to instability. When required, use
multiple large diameter vias because this lowers the equivalent
parasitic inductance.
GROUNDING
The use of ground and power planes is encouraged as a method
of proving low impedance returns for power supply and signal
currents. Ground and power planes can also help to reduce stray
trace inductance and provide a low thermal path for the amplifier.
Ground and power planes should not be used under any of the
pins of the AD8003. The mounting pads and the ground or power
planes can form a parasitic capacitance at the amplifiers input.
Stray capacitance on the inverting input and the feedback
resistor form a pole, which degrades the phase margin, leading
to instability. Excessive stray capacitance on the output also forms a
pole, which degrades phase margin.
