Within limits, the AD8337 preamplifier gain is controlled by
Resistor RFB1 and Resistor RFB2. See the
for rules applying to the current-feedback preamplifier. Figure 5,
Figure 6, and Figure 7 are schematics for the various circuit
configurations.

OUTPUT PROTECTION
The AD8337 VGA output stage is specified for driving loads of
500 Ω or greater. To protect the stage from accidental overload,
a 453 Ω resistor is provided which, when connected to 50 Ω test
equipment inputs, enables safe operation. In certain high load
impedance situations, the user can reduce the value of this
resistor; however, if load capacitance values greater than
approximately 20 pF are anticipated, such as a BNC cable, the
minimum series resistor value should not be less than 20 Ω.
An alternate test pin is also provided for direct access to the
output of the
probe, and a 0 Ω resistor is provided between the test loop and
the output pin. If the test loop is connected to loads ≤500 Ω,
then the 0 Ω resistor should be changed to an appropriate value.
