NOTES:
6.2.4
This pin provides the capacitor connection for setting the parameters of the microphone AGC circuit. It
should have a 4.7 μF capacitor connected to ground. It cannot be left floating. This is because the
capacitor is also used for the AutoMute circuit. This circuit reduces the amount of noises present in the
output during quiet pauses. Tying this pin to ground gives maximum gain; to V
for the AGC amplifier but will cancel the AutoMute function.
