3W Audio Power Amplifier with Shutdown Mode
LM4871 Audio Power Amplifier with Shutdown Mode
General Description

The LM4871isa mono bridged audio power amplifier ca-
pableof delivering 3Wof continuous average power intoa load with less than 10% THD when poweredbya5V
power supply (Note1).To conserve powerin portable appli-
cations, the LM4871’s micropower shutdown mode(IQ=
0.6µA, typ)is activated when VDDis appliedto the SHUT-
DOWN pin.
Boomer audio power amplifiers are designed specificallyto
provide high power, high fidelity audio output. They require
few external components and operateon low supply volt-
ages from 2.0Vto 5.5V. Sincethe LM4871 doesnot require
output coupling capacitors, bootstrap capacitors,or snubber
networks,itis ideally suitedfor low-power portable systems
that require minimum volume and weight.
Additional LM4871 features include thermal shutdown pro-
tection, unity-gain stability, and external gain set.
Note1:
An LM4871LDthat hasbeen properlymountedtoa circuit boardwill
deliver3Winto3Ω(at 10% THD).The other package optionsforthe LM4871
will deliver 1.5Winto8Ω(at 10% THD). Seethe Application Information
sectionsfor further information concerningthe LM4871LD, LM4871MM,
LM4871M,andthe LM4871N.
