Description

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 comparators 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.
