IS31AP4088A

IS31AP4088A DUAL 2.84W STEREO AUDIO AMPLIFIER PLUS HEADPHONE DRIVER January 2012 GENERAL DESCRIPTION The IS31AP4088A is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.84W to a 4Ω load. 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.
