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
current feedback amplifiers, do not use a capacitor across
R
loop reduces the amplifier’s stability. Instead, reduced peak-
ing in the frequency response, and bandwidth limiting can be
accomplished by adding an RC circuit, as illustrated in Fig-
ure 7b.

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