265mw At 3.3v Supply Audio Power Amplifier With Shutdown Mode - National SemiconductorThe LM4900 is a bridged Audio Power Amplifier capable of
delivering 265mW of continuous average power into an 8
load with 1% THD+N from a 3.3V power supply.
Boomer Audio Power Amplifiers were designed specifically
to provide high quality output power from a low supply volt-
age while requiring a minimal amount of external compo-
nents. Since the LM4900 does not require output coupling
capacitors, bootstrap capacitors or snubber networks, it is
optimally suited for low-power portable applications.
The LM4900 features an externally controlled, low power
consumption shutdown mode, and thermal shutdown protec-
tion.
The closed loop response of the unity-gain stable LM4900 CAN be configured by external gain-setting resistors. By National Semiconductor Corporation
