LM4867 Datasheet Dual 2.1w Audio Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4867 Output-Transient-Free Dual 2.1W Audio Amplifier Plus No Coupling Capacitor Stereo Headphone Function February 2001 LM4867 Output-Transient-Free Dual 2.

General Description

The LM4867 is a dual bridge-connected audio power amplifier which, when connected to a 5V supply, will deliver 2.1W to a 4Ω load (Note 1) or 2.4W to a 3Ω load (Note 2) with less than 1.0% THD+N.

The LM4867 uses advanced, latest generation circuitry to eliminate all traces of clicks and pops when the supply voltage is first applied.

The amplifier has a headphone-amplifier-select input pin.

Key Features

  • an externally controlled power-saving micropower shutdown mode, a stereo headphone amplifier mode, and thermal shutdown protection. Note 1: An LM4867LQ or LM4867MTE that has been properly mounted to a circuit board will deliver 2.1W into 4Ω. The Mux control can also be used to select two different closed-loop responses. LM4867MT will deliver 1.1W into 8Ω. See the.
