Typical Applications
CAPACITIVE FEEDBACK
For voltage feedback amplifiers it is quite common to place a
small lead compensation capacitor in parallel with feedback
resistance, R
plifier’s peaking in the frequency domain which equivalently
tames the transient response. To limit the bandwidth of cur-
rent feedback amplifiers, do not use a capacitor across R
The dynamic impedance of capacitors in the feedback loop
reduces the amplifier’s stability. Instead, reduced peaking in
the frequency response, and bandwidth limiting can be ac-
complished by adding an RC circuit, as illustrated in Figure
7b .

Characteristics
OVERDRIVE RECOVERY
When the output or input voltage range of a high speed am-
plifier is exceeded, the amplifier must recover from an over-
drive condition. The typical recovery times for open-loop,
closed-loop, and input common-mode voltage range over-
drive conditions are illustrated in Figures 9, 11, 11, 12 re-
spectively.
The open-loop circuit of Figure 8 generates an overdrive re-
sponse by allowing the
put range of the amplifier. Typical positive and negative over-
drive recovery times shown in Figure 9 are 5 ns and 25 ns,
respectively.
