LM4928 1.2 Watt Stereo Fully Differential Audio Power Amplifier with RF Suppression and
Shutdown Low
February 2006
LM4928
1.2 Watt Stereo Fully Differential Audio Amplifier with RF
Suppression and Shutdown Low
General Description
The LM4928 is an stereo fully differential stereo audio power
amplifier primarily designed for demanding applications in
mobile phones and other portable communication devices. It
is capable of delivering 1.2 watts of continuous average
power to a 8鈩?load with less than 1% distortion (THD+N)
from a 5V
DC
power supply.
Boomer audio power amplifiers were designed specifically to
provide high quality output power with a minimal amount of
external components. The LM4928 does not require output
coupling capacitors or bootstrap capacitors, and therefore is
ideally suited for mobile phone and other low voltage appli-
cations where minimal power consumption is a primary re-
quirement.
The LM4928 features a low-power consumption shutdown
mode. To facilitate this, shutdown may be enabled by logic
low. Additionally, the LM4928 features an internal thermal
shutdown protection mechanism.
The LM4928 contains advanced pop & click circuitry which
eliminates noises which would otherwise occur during
turn-on and turn-off transitions.
