FAQ
How is the mute circuit activated?
The mute circuit operates when pin 13 is connected to VCC during startup. It can also be forced to operate by connecting pin 16 to VCC.
What determines the time constant for the power-on mute circuit?
The time constant is determined by the capacitor connected between pins 14 and 15.
How is the bias point established?
Pins 3 and 4 are shorted and connected to earth via an electrolytic capacitor to generate the bias point.
