The feedback resistance (RF || RG) combines with the input
capacitance to form a pole in the amplifier’s loop response. This
can cause peaking and ringing in the amplifier’s response if the
RC time constant is too low. Figure 55 illustrates this effect.
Peaking can be reduced by adding a small capacitor (1 pF–4 pF)
across the feedback resistor. The best way to find the optimal
value of capacitor is to empirically try it in your circuit. Another
factor of higher resistance values is the impact it has on noise
performance. Higher resistor values generate more noise. Each
application is unique and therefore a balance must be reached
between distortion, peaking, and noise performance. Table 5
outlines the trade-offs that different loads have on distortion,
peaking, and noise performance. In gains of 1, 2, and 10,
equivalent loads of 1 k, 2 k, and 5 k are shown.
With increasing load resistance, the distortion and –3 dB
bandwidth improve, while the noise and peaking degrade
slightly.

DISABLE PIN
The AD8029 disable pin allows the amplifier to be shut down
for power conservation or multiplexing applications. When in
the disable mode, the amplifier draws only 150 A of quiescent
current. The disable pin control voltage is referenced to the
negative supply. The amplifier enters power-down mode any
time the disable pin is tied to the most negative supply or within
0.8 V of the negative supply. If left open, the amplifier will
operate normally. For switching levels, refer to Table 6.
