LM4871MM/NOPB (TEXAS INSTRUMENTS)

The LM4871MM/NOPB is a mono bridged Audio Power Amplifier capable of delivering 3W of continuous average power into a 3R 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 = 0.6µA, typical) is activated when VDD is applied to the shutdown pin. Boomer audio power amplifier is designed specifically to provide high power, high fidelity audio output. It requires few external components and operates on low supply voltages from 2.0 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.
