A2222 Datasheet | AiT Semiconductor

AiT Semiconductor Inc. .ait-ic. AUDIO POWER AMPLIFIER DUAL 2.2W PLUS STEREO HEADPHONE FUNCITON DESCRIPTION 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. 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 ponents. To simplify audio system design, the A2222 bines dual bridge speaker amplifiers and stereo headphone amplifiers on...
