APPLICATION INFORMATION
WIDEBAND, NONINVERTING OPERATION
The THS3091/5 are unity gain stable 235-MHz
current-feedback operational amplifiers, designed to
operate from a
±
5-V to
±
15-V power supply.
Figure 59 shows the THS3091 in a noninverting gain
of 2-V/V configuration typically used to generate the
performance
curves.
Most
characterized using signal sources with 50-
source
impedance,
and
with
measurement
presenting a 50-
load impedance.

Current-feedback amplifiers are highly dependent on
the feedback resistor R
for maximum performance
and stability. Table 1 shows the optimal gain-setting
resistors R
F
and R
G
at different gains to give
maximum bandwidth with minimal peaking in the
frequency response.
Higher
achieved, at the expense of added peaking in the
frequency response, by using even lower values for

Conversely,
