LM4906 Overview
The LM4906 is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable munication device applications. It is capable of delivering 1W of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a +5V power supply. The LM4906 is the first Texas Instruments Boomer Power Amplifier that does not require an external PSRR bypass capacitor.
