... Home Theater systems GENERAL DESCRIPTION PA4201 (PUNK low power (ICC < 1µA) monolithic CMOS mixed signal device. PUNK’s primary function is to control power supply transition noise in audio circuits and systems. PUNK boasts several features that make it a “one of a kind” product on the market. Most prominent is the feature that allows the designer to implement SOFT mute on an audio line during normal operation ...

... PA4201-PUNK POP-UP NOISE KILLER -THEORY OF OPERATION Startup During Startup, the power supply ramps from 0V to VCC. This time is usually in excess of 20ms. As soon as this change in voltage is sensed, PUNK latches the Mute Controller outputs to HIGH, thus “muting” the lines. This is the Startup Operation (figure 1). The duration for which for which the controller outputs are latched HIGH can be controlled by an external RC circuit ...
