1.1W Audio Power Amplifier With Logic Low Shutdown

The LM4876 is a single 5V supply bridge-connected Audio Power Amplifier capable of delivering 1.1W (typ) of continuous average power to an 8 load with 0.5% THD+N.
Like other Audio Amplifiers in the Boomer series, the LM4876 is designed specifically to provide high quality output power with a minimal amount of external components. The LM4876 does not require output coupling capacitors, bootstrap capacitors, or snubber networks. It is perfectly suited for low-power portable systems.
The LM4876 features an active low externally controlled, micro-power shutdown mode. Additionally, the LM4876 features an internal thermal shutdown protection mechanism. For PCB space efficiency, the LM4876 is available in MSOP and SO surface mount packages.
The unity-gain stable LM4876 's closed loop gain is set using external resistors.
