The input capacitance of the MAX4102/MAX4103 is
approximately 2pF. In either the inverting or noninvert-
ing configuration, the bandwidth limit caused by the
package capacitance and resistor time constant is
f3dB= 1 / (2
Π
RC), where R is the parallel combination
of the input and feedback resistors (RF and RG in
Figure 2) and C is the package and board capacitance
at the inverting input. R
S1
and R
S2
represent the input
termination resistors. Table 1 shows the typical band-
width and resistor values for several gain configura-
tions.
Resistor T ypes
Surface-mount resistors are the best choice for high-
frequency circuits. They are of similar material to the
metal-film resistors, but are deposited using a thick-film
process in a flat, linear manner so that inductance is
minimized. Their small size and lack of leads also mini-
mize parasitic inductance and capacitance, thereby
yielding more predictable performance.
