LM4872 October 2002 1 LM4872 Watt 1 Watt Audio Power Amplifier in micro SMD packageGeneral Description Key Specifications Audio The LM4872 is a bridge-connected audio power amplifier n Power Output at 0.2% THD 1W (typ) capable of delivering 1 W of continuous average power to an n Shutdown Current 0.01µA (typ) 8 load with less than .2% (THD) from a 5V power supply. Power Boomer audio power amplifiers were designed specifically to Features provide high quality output power with a minimal amount of n micro SMD package (see App. note AN-1112) external components. Since the LM4872 does not require n 5V - 2V operation output coupling capacitors or bootstrap capacitors. It is op- n No output coupling capacitors or bootstrap capacitors. timally suited for low-power portable applications. Amplifier n Unity-gain stable The LM4872 features an externally controlled, low-power n External gain configuration capability consumption shutdown mode, as well as an internal thermalshutdown protection mechanism. Applications The unity-gain stable LM4872 can be configured by externalgain-setting resistors. n Cellular Phones n Portable Computers micro n Low Voltage Audio Systems Typical Application SMD package 10123001 FIGURE 1.
