Inverting and Noninverting Configurations
Select the gain-setting feedback (R
F
) and input (R
G
)
resistor values that best fit the application. Large resis-
tor values increase voltage noise and interact with the
amplifier
’
s input and PC board capacitance. This can
generate undesirable poles and zeros and decrease
bandwidth or cause oscillations. For example, a nonin-
verting gain-of-two configuration (R
F
= R
G
) using 1k
resistors, combined with 1.8pF of amplifier input capac-
itance and 1pF of PC board capacitance, causes a
pole at 114MHz. Since this pole is within the amplifier
bandwidth, it jeopardizes stability. Reducing the 1k
resistors to 100
extends the pole frequency to
1.14GHz, but could limit output swing by adding 200
in parallel with the amplifier
’
s load resistor.
Note:
For high-gain applications where output offset
voltage is a consideration, choose R
S
to be equal to the
parallel combination of R
F
and R
G
(Figures 3a and 3b):
Video Line Driver
The MAX4412/MAX4413 are designed to minimize dif-
ferential gain error and differential phase error to 0.01%/
0.03
°
respectively, making them ideal for driving video
loads.
Active Filters
The low distortion and high bandwidth of the
MAX4412/MAX4413 make them ideal for use in active
filter circuits. Figure 4 is a 15MHz lowpass, multiple-
feedback active filter using the MAX4412.
