Inverting and Noninverting Configurations
Select the gain-setting feedback (RF) and input (RG)
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 (RF = RG) using 1kΩ
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
Ω
resistors to 100
Ω extends the pole frequency to
1.14GHz, but could limit output swing by adding 200
Ω
in parallel with the amplifier’s load resistor.
Note: For high-gain applications where output offset
voltage is a consideration, choose RS to be equal to the
parallel combination of RF and RG (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.
