The choice of feedback resistor is not critical unless it is
important to maintain the widest, flattest frequency response.
The resistors recommended in the table are those (chip
resistors) that will result in the widest 0.1 dB bandwidth without
peaking. In applications requiring the best control of bandwidth,
1% resistors are adequate. Package parasitics vary between the
14-pin plastic DIP and the 14-pin plastic SOIC, and may result
in a slight difference in the value of the feedback resistor used to
achieve the optimum dynamic performance. Resistor values and
widest bandwidth figures are shown in parenthesis for the SOIC
where they differ from those of the DIP. Wider bandwidths than
those in the table can be attained by reducing the magnitude of
the feedback resistor (at the expense of increased peaking),
while peaking can be reduced by increasing the magnitude of
the feedback resistor.
