Part Details:

LM4816 October 2003 1W LM4816 Stereo 1W Stereo Audio Amplifier + Adjustable Output LimiterGeneral Description Key Specifications The LM4816 combines a bridged-connected (BTL) stereo j P (BTL): OUT audio power amplifier with an adjustable output voltage mag- Audio V = 5V, THD = 1%, R = 8 1.0W (typ) nitude limiter. The audio amplifier delivers 1.0W to an 8 DD L load with less than 1.0% THD+N while operating on a 5V j Power supply range 3.0V to 5.5V power supply. With V set to 1.0V, the amplifier outputs are LIM j Limiter adjustment range GND to V /2 DD clamped to 6V , ±800mV. p-p j Shutdown current 0.06µA (typ) Amplifier The LM4816 features an external controlled micropowershutdown mode and thermal shutdown protection. It alsoutilizes circuitry that reduces "clicks and pops" during device Features turn-on and return from shutdown. n Stereo BTL amplifier Boomer audio power amplifiers are designed specifically to n Adjustable output voltage magnitude limiter use few external components and provide high quality output n "Click and pop" suppression circuitry power in a surface mount package. + n Unity-gain stable audio amplifiers Adjustable n Thermal shutdown protection circuitry n TSSOP (MT) package Applicationsn Notebook computers n Multimedia monitors n Desktop computers Output n Portable televisions Typical Application
