RECOMMENDED COMPONENTS VALUES
Table I summarizes recommended component values for
optimum flat frequency response. The recommended values
were determined with a 100 load resistance and a 2pF load
capacitance. Some adjustment of circuit values may be
required, especially with higher load capacitance. According
to the behavior shown in Figure 12, the frequency response
will show a peaking when the R
roll off more gradually when R
capacitor is responsible for the first open-loop pole and a
small external capacitor for the gains +1V/V and +2V/V is

required for stable operation. The package pins, the internal
lead frame, and bond wires form a resonant circuit. A
resistor in the range of 150 to 390 in series with all high
impedance inputs will damp the package related resonant
circuit. Also, the feedback resistor R
