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.
