The LM4850 can automatically switch between mono BTL and stereo SE modes utilizing a headphone sense pin. It is ideal for any system that provides both a monaural speaker output and a stereo line or headphone output Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. Since the LM4850 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The LM4850 features an externally controlled, micropower consumption shutdown mode and thermal shutdown protection. The unity-gain stable LM4850's gain is set by external gain-setting resistors
