General Description
The LM4871 is a mono bridged audio power amplifier capable of delivering 3W of continuous average power
into a 3Ohm load with less than 10% THD when powered by a 5V power supply . To conserve power in
portable applications, the LM4871's micropower shutdown mode (IQ = 0.6A, typ) is activated when VDD is
applied to the SHUTDOWN pin.
Boomer audio power amplifiers are designed specifically to provide high power, high fidelity audio output.
They require few external components and operate on low supply voltages from 2.0V to 5.5V. Since the
LM4871 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is ideally
suited for low-power portable systems that require minimum volume and weight.
Additional LM4871 features include thermal shutdown protection, unity-gain stability, and external gain set.
