Figure 80, Figure 81, and Figure 82 are schematics for the
various circuit configurations. Within limits, the AD8337
preamplifier gain is controlled by Resistor RFB1 and Resistor
RFB2. For simple guidelines applying to the current-feedback
preamplifier, see the Theory of Operation section.
OUTPUT PROTECTION
The AD8337 VGA output stage is specified for driving loads of
500 Ω or greater. To protect the stage from an 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 value of this resistor can be
reduced. However, if load capacitance values greater than
approximately 20 pF are anticipated, such as a BNC cable, the
minimum series resistor value is not to be less than 20 Ω.
An alternate test pin is also provided for direct access to the
output of
the AD8337 VGA. The pin is typically used for a
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 is to be changed to an appropriate value.
