DC Gain (Non-Inverting)
The non-inverting DC voltage gain for the configuration
shown in Figure 1 is:
A
V
Figure 1: Non-Inverting Gain
The normalized gain plots in the
Typical Performance
Characteristics
section show different feedback resistors,
R
f
, for different gains. These values of R
f
are recom-
mended for obtaining the highest bandwidth with minimal
peaking. The resistor R
t
in Figure 1 provides DC bias for
the non-inverting input.
For A
v
≤
5, calculate the recommended R
f
as follows:
R
f
340 - A
v
R
i
, where R
i
= 45
. For A
v
> 5, the
minimum recommended feedback resistor is R
f
= 100
.
Select R
g
to set the DC gain:
Accuracy of DC gain is usually limited by the tolerance of
the external resistors R
f
and R
g
.
DC Gain (Unity Gain Buffer)
Unity gain buffers are easily designed with a current-
feedback amplifier as long as the recommended feed-
back resistor R
f
= 402
is used and R
g
=
∞
, i.e. open.
Parasitic capacitance at the inverting node may require a
slight increase of the feedback resistor R
f
to maintain a
flat frequency response.

in Figure 2 is:
