APPLICATION INFORMATION
OVERDRIVE RECOVERY
Overdrive of an amplifier occurs when the output and/or input
range is exceeded. The amplifier must recover from this over-
drive condition. As shown in Figure 41, the AD8051/AD8052/
AD8054 recover within 60 ns from negative overdrive and
within 45 ns from positive overdrive.

DRIVING CAPACITIVE LOADS
Consider the AD8051/AD8052 in a closed-loop gain of +1 with
and Figure 43 show their frequency and time domain responses,
respectively, to a small-signal excitation. The capacitive load
drive of the AD8051/AD8052/AD8054 can be increased by
adding a low value resistor in series with the load. Figure 44
and Figure 45 show the effect of a series resistor on the capaci-
tive drive for varying voltage gains. As the closed-loop gain is
increased, the larger phase margin allows for larger capacitive
loads with less peaking. Adding a series resistor with lower
closed-loop gains accomplishes the same effect. For large
capacitive loads, the frequency response of the amplifier is
dominated by the roll-off of the series resistor and the load
capacitance.
