LM4866
2.2W Stereo Audio Amplifier
General Description
The LM4866 is a bridge-connected (BTL) stereo audio
power amplifier which, when connected to a 5V supply,
delivers 2.2W to a 4
load (Note 1) or 2.5W to a 3
load
(Note 2) with less than 1.0% THD+N.
With the LM4866 packaged in the LLP, the customer benefits
include low thermal impedance, low profile, and small size.
This package minimizes PCB area and maximizes output
power.
The LM4866 features an externally controlled, low-power
consumption shutdown mode, and thermal shutdown protec-
tion. It also utilizes circuitry to reduce “clicks and pops”
during device turn-on.
Boomer audio power amplifiers are designed specifically to
use few external components and provide high quality output
power in a surface mount package.
Note 1:
An LM4866MTE or LM4866LQ that has been properly mounted to
a circuit board will deliver 2.2W into 4
. The other package options for the
LM4866 will deliver 1.1W into 8
. See the Application Information sections
for further information concerning the LM4866MTE and LM4866LQ.
Note 2:
An LM4866MTE or LM4866LQ that has been properly mounted to a
circuit board will deliver 2.5W into 3
.
