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. This allows any pops to be dissipated
within the system before the switch settles into a closed position.
The NLAS6234 operates off of a single supply voltage, V_CC, and is
available in an ultra-thin UQFN10 package.
