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 components.
To simplify audio system design, the A2222 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip.
The A2222 features an externally controlled, low-power consumption shutdown mode, a stereo headphone amplifier mode, and thermal shutdown protection.
It also utilizes circuitry to reduce “clicks and pops” during device turn-on.
The A2222 is available in SOP16 package.
