1.1 Watt Audio Power AmplifierThe LM4879 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 1.1 watt of continuous average power to an 8
BTL load with less than 1% distortion (THD+N) from a 5VDC
power supply.
Boomer Audio Power Amplifiers were designed specifically to
provide high quality output power with a minimal amount of
external components. The LM4879 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 LM4879 features a low-power consumption global shut-
down mode, which is achieved by driving the shutdown pin
with Logic low. Additionally, the LM4879 features an internal
thermal shutdown protection mechanism.
The LM4879 contains advanced pop & click circuitry which
eliminates noises which would otherwise occur during
turn-on and turn-off transitions.
The LM4879 is unity-gain stable and CAN be configured by
external gain-setting resistors. By National Semiconductor Corporation
