Application Notes (Continued)
To improve power supply ripple rejection of the above micro-
phone preamplifier, another capacitor and a pot can be con-
nected to pin 1 as shown in
Figure 6. The impedance of the
two capacitors at audio frequencies are low. The R
POT can
be adjusted so that the supply ripples injected through both
the inverting input and the non-inverting input cancel each
other at the output. If we ignore the impedance of the capaci-
tors, we can select the pot value based on the following
equation:
Z
OUT is the output impedance of the microphone, and G is
the gain of the preamplifier in absolute value.
6.0 Adjustable-Gain Amplifier
The LMV101/102/105/110 not only provides fixed gain of −1,
−2, −5, and −10, it can also be configured for different gains
by adding only one external resistor.
You can decrease the gain by putting a resistor in series with
pin1(
Figure 7). You can increase the gain by connecting a
resistor from pin 1 to pin 3 (
Figure 8).
If you are using the LMV110 as a microphone preamplifier
for an electret microphone (
Figure 5), and the output imped-
ance of the microphone is 1k
Ω, then the gain of the pream-
plifier is
If we choose a small value for R, then we could get a pream-
plifier with a gain close to 100 (40dB), which is 10 times the
gain provided by LMV110.
