... ANALOG PRODUCTS DIVISION THEORY OF OPERATION STARTUP During Startup, the Power supply ramps from critical that this rise time be around 50ms for the PA4220 to perform well. This sudden rise in V causes the DC Blocking CC Capacitor to charge and thereby the pop up noise. The PA4220 senses this sudden change in voltage and clamps the output line to a low impedance state and suppresses the Pop noise ...
