The MAX9892 is an audio click-and-pop eliminator for
portable multimedia devices. Operating from a 1.7V to
3.6V supply, the MAX9892 connects to the output of the
existing system amplifier and provides a low-imped-
ance path to ground during startup and shutdown. The
inputs INL and INR accept voltage swings from V
5.5V below V
section for more information. The power-up and power-
down transients are shunted to ground to prevent clicks
and pops from becoming audible.
The MAX9892 features two low-impedance analog
switches controlled by MUTE that opens and closes the
switches. The switches are open during normal opera-
tion and have no impact on the output signal. During
startup and shutdown of the amplifier, the MAX9892
can be activated to short the outputs to ground and
prevent clicks and pops from pulling current through
the headphones.
The MAX9892 is available in 6-bump UCSP (1mm x
1.52mm x 0.6mm) and 6-pin µDFN (2mm x 2mm x
0.75mm) packages. The MAX9892 is specified over the
-40°C to +85°C temperature range.
