A2222 DUAL 2.2W PLUS STEREO HEADPHONE AUDIO POWER AMPLIFIER

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. Boome.
