1 / 16 page  IS31AP4088D Integrated Silicon Solution, Inc. – www.issi.com Rev.A, 11/29/2011 1 DUAL 2.6W STEREO AUDIO AMPLIFIER December 2011 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 KEY SPECIFICATIONS PO at 1% THD+N, VDD = 5V RL = 4Ω ----------------------- 2.1W (Typ.)
