LM4923 Datasheet 1.1 Watt Fully Differential Audio Power Amplifier

Manufacturer: Texas Instruments

Overview: LM4923, LM4923LQBD www.ti.com SNAS211E – JULY 2004 – REVISED MAY 2013 LM4923 1.

General Description

The LM4923 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 1.1 watt of continuous average power to an 8Ω BTL load with less than 1% 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.
