The MAX4910ETE+ is a quad SPDT, clickless audio switches with negative signal handling in 16 pin TQFN package. The device feature negative signal capability that allows signals as low as VCC-5.5V to pass through without distortion. This analogue switch has a low on-resistance, low supply current and operates from a single +1.8V to +5.5V supply. The MAX4910 has internal shunt resistors that automatically discharge the capacitance at the normally open (NO) and normally closed (NC) terminals when it is not connected. The MAX4910 has shunt resistors on all NO and NC terminals. These shunt resistors reduce click-and pop sounds that occur when switching audio signals between precharged points. A break-before-make feature further reduces popping. The MAX4910 control the switches in pairs with two control bits CB1 and CB2. This device is used in cell phones, PDAs, handheld devices, notebook computers and MP3 players.
