1 / 16 page LM4863 Dual 2.2W Audio Amplifier Plus Stereo Headphone Function General Description The LM4863 is a dual bridge-connected audio power ampli- fier which, when connected to a 5V supply, will deliver 2.2W toa4 Ω load (Note 1) or 2.5W to a 3Ω load (Note 2)with less than 1.0% THD+N. In addition, the headphone input pin al- lows 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 sim- plify audio system design, the LM4863 combines dual bridge speaker amplifiers and stereo headphone amplifiers on one chip. The LM4863 features an externally controlled, low-power consumption shutdown mode, a stereo headphone amplifier mode, and thermal shutdown protection. It also utilizes cir- cuitry to reduce “clicks and pops” during device turn-on. Note 1: An LM4863MTE which has been properly mounted to the circuit board will deliver 2.2W into 4 Ω. The other package options for the LM4863 will deliver 1.1W into 8 Ω. See the Application Information section for LM4863MTE usage information. Note 2: An LM4863MTE which has been properly mounted to the circuit board and forced-air cooled will deliver 2.5W into 3 Ω.
