The APA2192 is an audio click-and-pop eliminator for
portable multimedia devices. Operating from a 1.7V to 3.
6V supply, the APA2192 connects to the output of the ex-
isting system amplifier and provides a low-impedance
path to ground during startup and shutdown. The inputs
INL and INR accept voltage swings from V to 5.5V below
DD
VDD. See the Setting the Supply Voltage section for more
information. The power-up and power down transients
are shunted to ground to prevent clicks and pops from
becoming audible.
The APA2192 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 APA2192 can be acti-
vated to short the outputs to ground and prevent clicks
and pops from pulling current through the headphones.
