General Description
The MAX4908/MAX4909/MAX4930/MAX4932 dual 3:1
clickless audio multiplexers feature negative-signal
capability that allows signals as low as VCC - 5.5V to
pass through without distortion. These analog multiplex-
ers have a low on-resistance (0.38Ω), low supply current,
and operate from a single +1.8V to +5.5V supply.
The MAX4908 has shunt resistors on all input terminals,
and the MAX4909 has shunt resistors on all input termi-
nals except X0 and Y0. The MAX4930 has shunt resistors
only on the X2 and Y2 terminals, and the MAX4932 has
no shunt resistors. The shunt resistor feature reduces
click-and-pop sounds by automatically discharging the
capacitance at the input terminal when they are not con-
nected. A break-before-make feature further reduces
popping.
The MAX4908/MAX4909/MAX4930/MAX4932 use two
digital control inputs CB1 and CB2 to switch between sig-
nals. The digital control inputs can accept up to +5.5V
independent of the supply voltage.
The MAX4908/MAX4909/MAX4930/MAX4932 are avail-
able in 12-bump WLP and 14-pin TDFN-EP packages
and operate over the -40°C to +85°C extended temper-
ature range.
