MAX4762, MAX4763, MAX4764, MAX4764A, MAX4765
Low-Voltage, Dual SPDT, Audio Clickless Switches with Negative Rail Capability
|
Status
Active: In Production.
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.
