LM4954 High Voltage 3 Watt Audio Power Amplifier
June 2005
LM4954
High Voltage 3 Watt Audio Power Amplifier
General Description
The LM4954 is an audio power amplifier primarily designed
for demanding applications in mobile phones and other por-
table communication device applications. It is capable of
delivering 2.4 Watts of continuous average power to an 8鈩?/div>
BTL load with less than 1% THD+N from a 7V
DC
power
supply.
Boomer audio power amplifiers are designed specifically to
provide high quality output power with a minimal number of
external components. The LM4954 does not require output
coupling capacitors or bootstrap capacitors, and therefore is
ideally suited for lower-power portable applications where
minimal space and power consumption are primary require-
ments.
The LM4954 features a low-power consumption global shut-
down mode which is achieved by driving the shutdown pin
with logic low. Additionally, the LM4954 features an internal
thermal shutdown protection mechanism.
The LM4954 contains advanced pop & click circuitry which
eliminates noises that would otherwise occur during turn-on
and turn-off transitions.
The LM4954 is unity-gain stable and can be configured by
external gain-setting resistors.
