LM4871MX/NOPB General Description
The LM4871 is a mono bridged audio power amplifier capable of delivering 3W of continuous average power into a 3Ω load with less than 10% THD when powered by a 5V power supply (see Note). To conserve power in portable applications, the LM4871's micropower shutdown mode (IQ = 0.6µA, 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.
Note: An LM4871LD that has been properly mounted to a circuit board will deliver 3W into 3Ω (at 10% THD). The other package options for the LM4871 will deliver 1.5W into 8Ω (at 10% THD). See the section for further information concerning the LM4871LD, LM4871MM, LM4871M, and the LM4871N.
