______________________________________________________________________________________
Coaxial cable and other transmission lines are easily
driven when properly terminated at both ends with their
characteristic impedance. Driving back-terminated
transmission lines essentially eliminates the line
s
capacitance.
___________Applications Information
Choosing Resistor Values
Unity-Gain Configuration
The MAX4414/MAX4416/MAX4418 are internally com-
pensated for unity gain. When configured for unity gain,
the devices require a 24
feedback resistor (R
F
). This
resistor improves AC response by reducing the Q of the
parallel LC circuit formed by the parasitic feedback
capacitance and inductance.
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
