LM4883 Datasheet Dual 2.1w Audio Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LM4883 Dual 2.1W Audio Amplifier Plus Stereo Headphone Function November 2004 LM4883 Dual 2.

General Description

The LM4883 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.

In addition, the headphone input pin allows the amplifiers to operate in single-ended mode when driving stereo headphones.

A MUX control pin allows selection between the two stereo sets of amplifier inputs.

Key Features

  • an internally 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 LM4883SQ that has been properly mounted to a circuit board will deliver 2.1W into 4Ω. See the.
