2 Watt Audio Power Amplifier with Selectable Shutdown Logic Level - General Description The LN4990A is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable munication device applications. It is capable of delivering 1.25 watts of continuous average power to an 8Ω B TL load and 2 watts of continuous average power (LD and MH only) to a 4Ω 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 ponents. The LN4990A does not require output coupling capacitors or bootstrap capacitors,...
