__________Applic ations Information
Power S upply
The MAX4005 allows for two separate +5V supplies for
the output stage and the rest of the MAX4005 circuit. The
supplies are bonded out separately to give the option of
using a different +5V supply. The output stage is a Class
A type, with the output transistor fed by a current source
in the emitter, so its current will vary with output signal.
For best bandwidth and pulse response, solder bypass
chip capacitors directly from the supply pins on the four
corners of the package to a ground plane.
Input Impedanc e
The MAX4005 has a J FET input with an input capaci-
tance of only 2pF. As a result, the leakage current is
typically less than 10pA. This exceptionally high input
impedance is important in applications that require iso-
lation between a high source impedance and a low-
impedance transmission cable. An attenuator may be
used in front of the MAX4005 to increase the dynamic
range and reduce input capacitance.
Output Impedanc e
A 75
precision thin-film output resistor is included on-
board to provide more precise reverse termination
than standard discrete resistors. This minimizes reflec-
tions caused by impedance mismatching when driving
transmission cable. The MAX4005 can also drive a
50
load with only a slight loss in amplitude (gain
drops from 0.5 to 0.4). The typical operating perfor-
mance specifications shown in the Electrical
Characteristics have been verified with a 50
load, as
well as a 75
load.
Frequenc y Response Peaking
To peak the response to compensate for losses when
driving long transmission lines, connect a chip capaci-
tor of about 10pF to 50pF between the PEAK pin and
ground. This peaking occurs in the 200MHz to 500MHz
range. The PEAK pin will normally be left open for flat-
test response.
