LM4877
1 Watt Audio Power Amplifier in micro SMD package
with Shutdown Logic Low
General Description
The LM4877 is a bridge-connected audio power amplifier ca-
pable of delivering 1 W of continuous average power to an
8
load with less than .2% (THD) 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. Since the LM4877 does not require
output coupling capacitors or bootstrap capacitors. It is opti-
mally suited for low-power portable applications.
The LM4877 features an externally controlled, low-power
consumption shutdown mode, as well as an internal thermal
shutdown protection mechanism.
The unity-gain stable LM4877 can be configured by external
gain-setting resistors.
