Application Information
(Continued)
The LM4892 is unity-gain stable and requires no external
components besides gain-setting resistors, an input coupling
capacitor, and proper supply bypassing in the typical appli-
cation. However, if a closed-loop differential gain of greater
than 10 is required, a feedback capacitor (C
f
) may be
needed as shown in Figure 3 to bandwidth limit the amplifier.
This feedback capacitor creates a low pass filter that elimi-
nates possible high frequency oscillations. Care should be
taken when calculating the -3dB frequency in that an incor-
rect combination of R
f
and C
f
will cause rolloff before 20kHz.
A typical combination of feedback resistor and capacitor that
will not produce audio band high frequency rolloff is R
f
=
20k
and C
= 25pF. These components result in a -3dB
point of approximately 320 kHz.
