LM4861
1.1W Audio Power Amplifier with Shutdown Mode
General Description
The LM4861 is a bridge-connected audio power amplifier ca-
pable of delivering 1.1W of continuous average power to an
8
load with 1% (THD) using a 5V power supply.
Boomer audio power amplifiers were designed specifically to
provide high quality output power with a minimal amount of
external components using surface mount packaging. Since
the LM4861 does not require output coupling capacitors,
bootstrap capacitors, or snubber networks, it is optimally
suited for low-power portable systems.
The LM4861 features an externally controlled, low-power
consumption shutdown mode, as well as an internal thermal
shutdown protection mechanism.
The unity-gain stable LM4861 can be configured by external
gain-setting resistors.
