AiT Semiconductor A2222
The A2222 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.2W to a 4Ω load or 2.5W to a 3Ω load with less than 1.0% THD+N. The A2222 features an externally controlled, low-power consumption shutdown mode, a stereo headphone amplifier mode, and thermal shutdown protection. To simplify audio system design, the A2222 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.| Part No. | A2222 |

DESCRIPTION
In addition, the headphone input pin allows the amplifiers to operate in single-ended mode to drive stereo headphones. Boomer audio power amplifiers were designed specifically to provide high quality output power from a surface mount package while requiring few external components. It also utilizes circuitry to reduce “clicks and pops” during device turn-on. The A2222 is available in SOP16 package. ORDERING INFORMATIONFEATURES
