DUAL 1.3W STEREO AUDIO AMPLIFIER

January 2014

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 8Ω load.

The IS31AP4066D features a low-power consumption

shutdown mode and thermal shutdown protection. It

also utilizes circuitry to reduce “click-and-pop” during

device turn-on.

APPLICATIONS

 Cell phones, PDA, MP4,PMP

 Portable and desktop computers

 Desktops audio system

 Multimedia monitors
