LN4871

3W Audio Power Amplifier With Shutdown Mode LN4871 ■ General Description The LN4871 is a bridge-connected audio power amplifier capable of delivering typically 3W of continuous average power to an 3Ω load with10% (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 LN4871 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is optionally suited for low-power portable systems. The LN4871 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable LN4871 can be configured by external gain-setting resistors. ■ Key Specifications  Power Output @10% THD+N & VDD=5V 1KHZ RL=3Ω 3W (TYP) RL=4Ω 2.5W (TYP)  THD+N@ 1KHZ 1W 8Ω 0.5%(MAX)  Shutdown current 0.1uA(TYP.)
