LM4927 Datasheet 2.5 Watt Fully Differential Audio Power Amplifier

Manufacturer: Texas Instruments

Overview: LM4927 www.ti.com SNAS318B – JUNE 2005 – REVISED APRIL 2013 LM4927 Boomer™ Audio Power Amplifier Series 2.

General Description

The LM4927 is a fully differential audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications.

It is capable of delivering 2.5 watts of continuous average power to a 4Ω load with less than 10% distortion (THD+N) from a 5VDC power supply.

Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components.
