GENERAL DESCRIPTION  
PA4201 (PUNK) is a 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. PUNK is an  
exceptional product for multi-channel devices as it is capable of expanding the SOFT mute operation into  
(Dolby 5.1 DTSTM) systems .  
PUNK requires few external components for its operation, working from low to medium power supply voltages  
of 2.7V to 5.5V. As soon as a change in the power supply is detected, PUNK ensures that audio inputs to  
succeeding amplifiers are switched to a convenient low impedance voltage rail. This causes the amplifiers to  
remain silent as the power supply changes state.  
PUNK operates as a passive shunt device. So the designer does not have to worry about PUNK introducing  
any kind of noise or distortion into the system.  
While consuming less than 1µA of supply current PUNK provides more than 45dB of mute attenuation at the  
audio lines.  
PUNK is equipped with ESD (Human Body Model) protection circuitry on the outputs.  
PUNK is available as an 8L low profile 0.6mm DFN as well as the SO-8 package and is specified for operation  
over the -40 to +85 deg. C temperature range.
