illustrate

The LM4871 is a mono bridged audio power amplifier delivered to 3 continuous average power 3W capability Powered by a 5V supply at less than 10% THD load. To save power for portable applications, V DD is applied to the SHUTDOWN pin when the LM4871's micropower shutdown mode (I Q = 0.6μA, typical) is activated.

Boomer audio power amplifiers are designed to provide high-power, high-fidelity audio output. They require few external components and operate at 2.0V to 5.5V at low supply voltages. Since the LM4871 does not require output coupled capacitors, bootstrap capacitors, or buffer networks, it is ideal for portable systems with low power consumption requirements for minimal volume and weight.

Other LM4871 features include thermal shutdown protection, unity gain stabilization, and external gain settings.
