LM4876
1.1W Audio Power Amplifier with Logic Low Shutdown
General Description
The LM4876 is a single 5V supply bridge-connected audio
power amplifier capable of delivering 1.1W (typ) of continu-
ous 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 ca-
pacitors, 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 fea-
tures 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.
