A2222 - DUAL 2.2W PLUS STEREO HEADPHONE AUDIO POWER AMPLIFIER

Datasheet Summary

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.

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.

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.
