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.
