The LM4910 is unity-gain stable and requires no external
components besides gain-setting resistors, input coupling ca-
pacitors, and proper supply bypassing in the typical applica-
tion. However, if a very large closed-loop differential gain is
required, a feedback capacitor (C
f) may be needed as shown
in Figure 6 to bandwidth limit the amplifier. This feedback ca-
pacitor creates a low pass filter that eliminates possible high
frequency oscillations. Care should be taken when calculating
the -3dB frequency in that an incorrect combination of R
f and
C
f will cause frequency response roll off before 20kHz. A typ-
ical combination of feedback resistor and capacitor that will
not produce audio band high frequency roll off is Rf = 20k
and C
f = 25pF. These components result in a -3dB point of
approximately 320kHz.
