Описание
The LM4871LD/NOPB is a 3W Audio Amplifier with shutdown mode 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. This Boomer audio power amplifier is designed specifically to provide high power, high fidelity audio output. They require few external components and operate on low supply voltages from 2V 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 features include thermal shutdown protection, unity-gain stability and external gain set.
• No output coupling capacitors, bootstrap capacitors or snubber circuits required
• Unity-gain stable
• External gain configuration capability
• Pin compatible with the LM4861
• Green product and no Sb/Br
