APPLICATION INFORMATION
MAXIMUM SLEW RATE FOR REPETITIVE
SIGNALS
Current-feedback amplifiers are highly dependent on
the feedback resistor R
F
for maximum performance
and stability. Table 1 shows the optimal gain setting
resistors R
F
and R
G
at different gains to give maxi-
mum
bandwidth
with
minimal
frequency response.

achieved, at the expense of added peaking in the
frequency response, by using even lower values for

Conversely,

bandwidth, but stability is improved.
The THS3110 and THS3111 are recommended for
high slew rate pulsed applications where the internal
nodes of the amplifier have time to stabilize between
pulses. It is recommended to have at least 20-ns
delay between pulses.

The THS3110 and THS3111 are not recommended
for applications with repetitive signals (sine, square,
sawtooth, or other) that exceed 900 V/
μ
s. Using the
part in these applications results in excessive current
draw from the power supply and possible device
damage.
