LM4915 Overview
The LM4915 is a pseudo-differential audio power amplifier primarily designed for demanding applications in mobile phones and other portable audio device applications with mono headphones. It is capable of delivering 90 miliwatts of continuous average power to a 32Ω BTL load with less than 1% distortion (THD+N) from a 3VDC power supply. Boomer audio power amplifiers were designed specifically to provide high quality...
