IS31AP4088A
DUAL 2.84W STEREO AUDIO AMPLIFIER PLUS HEADPHONE DRIVER
January 2012
GENERAL DESCRIPTION
KEY SPECIFICATIONS
The IS31AP4088A is a dual bridge-connected audio
power amplifier which, when connected to a 5V supply,
will deliver 2.84W to a 4load.
To simplify audio system design, the IS31AP4088A
combines dual bridge speaker amplifiers and stereo
headphone amplifiers on one chip.
The IS31AP4088A features a low-power consumption
shutdown mode and thermal shutdown protection. It
also utilizes circuitry to reduce “clicks and pops” during
device turn-on.
