LM4871
1.1W Audio Power Amplifier with Shutdown Mode
General Description
The LM4871 is a bridge-connected audio power amplifier ca-
pable of delivering typically 1.1W of continuous average
power to an 8
load with 0.5% (THD) from a 5V power sup-
ply.
Boomer audio power amplifiers were designed specifically to
provide high quality output power with a minimal amount of
external components. Since the LM4871 does not require
output coupling capacitors, bootstrap capacitors, or snubber
networks, it is optionally suited for low-power portable sys-
tems.
The LM4871 features an externally controlled, low-power
consumption shutdown mode, as well as an internal thermal
shutdown protection mechanism.
The unity-gain stable LM4871 can be configured by external
gain-setting resistors.
