LM4992 420mW Stereo Cell Phone Audio Amplifier
February 2004
LM4992
420mW Stereo Cell Phone Audio Amplifier
General Description
The LM4992 is a stereo audio power amplifier primarily
designed for demanding applications in mobile phones and
other portable communication device applications. It is ca-
pable of delivering 1 watt, per channel, of continuous aver-
age power to an 8鈩?BTL 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 LM4992 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 LM4992 features independent shutdown control for
each channel and a low-power consumption shutdown
mode, which is achieved by driving both shutdown pins with
logic low. Additionally, the LM4992 features an internal ther-
mal shutdown protection mechanism.
The LM4992 contains advanced pop & click circuitry which
eliminates noise which would otherwise occur during turn-on
and turn-off transitions.
The LM4992 is unity-gain stable and can be configured by
external gain-setting resistors.
