LM4876
1.1W Audio Power Amplifier with Logic Low Shutdown
General DescriptionThe LM4876isa single5V supply bridge-connected audio
power amplifier capableof delivering 1.1W (typ)of continu-
ous average powertoan8Ω load with 0.5% THD+N.
Like other audio amplifiersinthe Boomer series,the LM4876 designed specificallyto provide high quality output power
witha minimal amountof external components. The LM4876
does not require output coupling capacitors, bootstrap ca-
pacitors,or snubber networks.Itis perfectly suitedfor low-
power portable systems.
The LM4876 featuresan active low externally controlled,
micro-power shutdown mode. Additionally,the LM4876 fea-
turesan internal thermal shutdown protection mechanism.
For PCB space efficiency,the LM4876is availablein MSOP
and SO surface mount packages.
The unity-gain stable LM4876’s closed loop gainisset using
external resistors.
