NLAS6234
Audio DPDT Switch with Noise Suppression
Description The NLAS6234 is a DPDT switch featuring Popless noise
suppression circuitry designed to prevent pass through of undesirable transient signals known as pops. Intended for audio systems within portable applications, it provides protection against audible pops that are generated when switching between two different audio sources, such as an amplifier and a CODEC.
The NLAS6234 incorporates two double throw switches controlled by a single select line which allows the system controller to simultaneously switch between two sets of signal lines. The Popless noise suppression circuitry controls the ON and OFF times that define the time interval when switching between the normally open (NO) and normally closed (NC) terminals.
