0.5 Ohm Popless Dual SPDT Analog Switch

The NLAS6233 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 NLAS6233 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. This allows any pops to be dissipated within the system before the switch settles into a closed position. The NLAS6233 operates off of a single supply voltage, VCC. It is available in an ultra thin UQFN10 package.
