LM4855 Integrated Audio Amplifier System November 2002 LM4855 Integrated Audio Amplifier System General Description The LM4855 is an audio power amplifier system capable of delivering 1.1W (typ) of continuous average power into a mono 8Ω bridged-tied load (BTL) with 1% THD+N and 115mW (typ) per channel of continuous average power into stereo 32Ω BTL loads with 0.5% THD+N, using a 5V power supply. The LM4855 Features a 32 step digital volume control eight distinct output modes. The digital volume control output modes are programmed through a three-wire serial control interface, that allows flexibility in routing mixing audio channels. and and SPI and Key Specifications n THD+N at 1kHz,...
