DUAL 2.6W STEREO AUDIO AMPLIFIER
January 2014
GENERAL DESCRIPTION
The IS31AP4088D is a dual bridge-connected audio
power amplifier which, when connected to a 5V supply,
will deliver 2.6W to a 4Ω load.
The IS31AP4088D features a low-power consumption
shutdown mode and thermal shutdown protection. It
also utilizes circuitry to reduce “clicks-and-pop” during
device turn-on.
APPLICATIONS
Cell phones, PDA, MP4,PMP
Portable and desktop computers
Desktops audio system
Multimedia monitors
