LM4882
250mW Audio Power Amplifier with Shutdown Mode
General Description
The LM4882 is a single-ended audio power amplifier ca-
pable of delivering 250 mW of continuous average power
into an 8
load with 1% (THD + N) 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 using surface mount packaging.
Since the LM4882 does not require bootstrap capacitors or
snubber networks, it is optimally suited for low-power por-
table systems.
The LM4882 features an externally controlled, low power
consumption shutdown mode which is virtually clickless and
popless, as well as an internal thermal shutdown protection
mechanism.
The unity-gain stable LM4882 can be configured by external
gain-setting resistors.
