LM4889 Overview
The LM4889 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable munication device applications. It is capable of delivering 1 watt of continuous average power to an 8Ω BTL load with less than 2% 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...
