Description
The MAX4762–MAX4764/MAX4764A/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 0.6Ω on-resistance, 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/MAX4764A/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 operate over the -40°C to +85°C extended temperature range.
