The MAX4855 dual, single-pole/double-throw (SPDT)
switch operates from a single +2V to +5.5V supply and
features rail-to-rail signal handling. The MAX4855 has
low on-resistance (0.75Ω) with a +3V supply making it
ideal for audio switching applications in portable
devices. The device also integrates two internal com-
parators that can be used for headphone detection or
mute/send key functions.
The MAX4855 is available in the space-saving (3mm x
3mm), 16-pin thin QFN package and operates over the
extended temperature range of -40°C to +85°C.
