LM4863 Datasheet Dual 2.2w Audio Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4863 Dual 2.2W Audio Amplifier Plus Stereo Headphone Function October 1999 LM4863 Dual 2.

General Description

The LM4863 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.2W to a 4Ω 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 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.

Key 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. Note 1: An LM4863MTE which has been properly mounted to the circuit board will deliver 2.2W into 4Ω. The other package options for the LM4863 will deliver 1.1W into 8Ω. See the.
