Product Summary
The LM4871N is a bridge-connected audio power amplifier capable of delivering typically 1.1W of continuous average power to an 8W load with 0.5% (THD) from a 5V power supply. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. Since the LM4871N does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is optionally suited for low-power portable systems. The LM4871N features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The applications of the LM4871N include Portable Computers, Desktop Computers, Low Voltage Audio Systems.
