The MAX4910/MAX4911/MAX4912 quad, singlepole/double-throw (SPDT), clickless audio switches feature negative signal capability that allows signals as low
as VCC -5.5V to pass through without distortion. These analog switches have a low on-resistance, low supply current, and operate from a single +1.8V to +5.5V supply.
The MAX4910/MAX4911/MAX4912 have internal shunt resistors that automatically discharge the capacitance at the normally open (NO) and normally closed (NC) terminals when they are not connected. The MAX4910/MAX4911 have shunt resistors on all NO and NC terminals and the MAX4912 has shunt resistors on all NO, NC1, and NC3 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/MAX4912 control the switches in pairs with two control bits CB1 and CB2. The MAX4911 has one control bit to switch all four switches and an enable pin active-low EN to put the switches in a high-impedance mode. The MAX4912 has two terminals without shunt resistors for switching applications that do not require pre-discharge switching.
The MAX4910/MAX4911/MAX4912 are available in a tiny 16-pin TQFN-EP (3mm x 3mm) package and operate over the -40°C to +85°C extended temperature range.
