IS31AP4066D
DUAL 1.3W STEREO AUDIO AMPLIFIER
GENERAL DESCRIPTION
The IS31AP4066D is a dual bridge-connected audio
power amplifier which, when connected to a 5V supply,
will deliver 1.3W to an 8⦠load.
The IS31AP4066D features a low-power consumption
shutdown mode and thermal shutdown protection. It
also utilizes circuitry to reduce âclick-and-popâ during
device turn-on.
APPLICATIONS
ï· Cell phones, PDA, MP4,PMP
ï· Portable and desktop computers
ï· Desktops audio system
ï· Multimedia monitors
