LM4853
Mono 1.5 W / Stereo 300mW Power Amplifier
General Description
The LM4853 is an audio power amplifier capable of deliver-
ing 1.5W (typ) of continuous average power into a mono 4
bridged-tied load (BTL) with 1% THD+N or 95mW per chan-
nel of continuous average power into stereo 32
single-
ended (SE) loads with 1% THD+N, using a 5V power supply.
The LM4853 can automatically switch between mono BTL
and stereo SE modes utilizing a headphone sense pin. It is
ideal for any system that provides both a monaural speaker
output and a stereo line or headphone output
Boomer audio power amplifiers were designed specifically to
provide high quality output power with a minimal amount of
external components. Since the LM4853 does not require
bootstrap capacitors or snubber networks, it is optimally
suited for low-power portable systems.
The LM4853 features an externally controlled, micropower
consumption shutdown mode and thermal shutdown protec-
tion. The unity-gain stable LM4853’s gain is set by external
gain-setting resistors
