SNAS343F –OCTOBER 2005–REVISED APRIL 2013

LM4934 Boomer™ Audio Power Amplifier Series 3D Audio Sub-System with Stereo

Speaker, OCL/SE Stereo Headphone, Earpiece and Mono Line Level Outputs

Check for Samples: LM4934

FEATURES

DESCRIPTION

The LM4934 is an integrated audio sub-system

designed for stereo cell phone applications.

Operating on a 3.3V supply, it combines a stereo

speaker amplifier delivering 520mW per channel into

an 8Ω load, a stereo headphone amplifier delivering

36mW per channel into a 32Ω load, a mono earpiece

amplifier delivering 55mW into a 32Ω load, and a line

output for an external powered handsfree speaker. It

integrates the audio amplifiers, volume control, mixer,

power management control, and Texas Instruments

3D enhancement all into a single package. In

addition, the LM4934 routes and mixes the stereo

and mono inputs into multiple distinct output modes.

The LM4934 features an I2S serial interface for full

range audio and an I2C/SPI compatible interface for

control.
