General Description
The MAX4762–MAX4765 dual SPDT (single-pole/double-
throw) switches feature negative signal capability that
allows signals below ground to pass through without
distortion. These analog switches operate from a single
+1.8V to +5.5V supply and have low 0.6
on-resis-
tance, making them ideal for switching audio signals.
The MAX4763/MAX4765 include a comparator that can
be used for headphone detection or a mute/send key
function. The MAX4764/MAX4765 have an internal shunt
switch to automatically discharge any capacitance at the
NO and NC connection points. This reduces click-and-
pop sounds that occur when switching audio signals
between precharged points.
These SPDT switches are available in space-saving
μMAX, TDFN, thin QFN, and UCSP
packages and oper-
ate over the -40°C to +85°C extended temperature range.
