LM4991 Overview

The LM4991 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 (Note 1). To conserve power in portable applications, the LM4991’s micropower shutdown mode (ISD = 0.1µA, typ) is activated when VDD is applied to the SHUTDOWN pin. Boomer audio power amplifiers are designed specifically to provide high power,...
