LM4816
1W Stereo Audio Amplifier + Adjustable Output Limiter
General Description
The LM4816 combines a bridged-connected (BTL) stereo
audio power amplifier with an adjustable output voltage mag-
nitude limiter. The audio amplifier delivers 1.0W to an 8
load with less than 1.0% THD+N while operating on a 5V
power supply. With V
LIM set to 1.0V, the amplifier outputs are
clamped to 6V
p-p, ±800mV.
The LM4816 features an external controlled micropower
shutdown mode and thermal shutdown protection. It also
utilizes circuitry that reduces “clicks and pops” during device
turn-on and return from shutdown.
Boomer audio power amplifiers are designed specifically to
use few external components and provide high quality output
power in a surface mount package.
