General Description

The LM4674 is a single supply, high efficiency, 2.5W/ channel, filterless switching audio amplifier.

A low noise PWM architecture eliminates the output filter, reducing external component count, board area consumption, system cost, and simplifying design.

The LM4674 is designed to meet the demands of mobile phones and other portable communication devices.

Overview

www.DataSheet4U.com LM4674 Filterless 2.5W Stereo Class D Audio Power Amplifier December 2005 LM4674 Filterless 2.

Key Features

high efficiency compared to conventional Class AB amplifiers. When driving and 8Ω speaker from a 3.6V supply, the device features 85% efficiency at PO = 500mW. Four gain options are pin selectable through the GAIN0 and GAIN1 pins. Output short circuit protection prevents the device from being damaged during fault conditions. Superior click and pop suppression eliminates audible transients on power-up/down and during shutdown. Independent left/right shutdown controls maximizes power savings in mi.
