LM4816 Datasheet | National Semiconductor

Description The LM4816 bines a bridged-connected (BTL) stereo audio power amplifier with an adjustable output voltage magnitude limiter. The audio amplifier delivers 1.0W to an 8Ω load with less than 1.0% THD+N while operating on a 5V power supply. With VLIM set to 1.0V, the amplifier outputs are clamped to 6Vp-p, ± 800m V. The LM4816 features an external controlled micropower shutdown mode and thermal shutdown protection. It also utilizes circuitry that reduces “clicks and pops” during device turn-on and return from shutdown. Boomer audio power amplifiers are designed specifically to use few external ponents and provide high quality output power in a surface mount package.
