LM4853 Mono 1.5 W / Stereo 300mW Power Amplifier January 2003 LM4853 Mono 1.5 W / Stereo 300mW Power Amplifier General Description The LM4853 is an audio power amplifier capable of delivering 1.5W (typ) of continuous average power into a mono 4Ω bridged-tied load (BTL) with 1% THD+N or 95mW per channel of continuous average power into stereo 32Ω singleended (SE) loads with 1% THD+N, using a 5V power supply. The LM4853 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...
