The LM4674ATLX/NOPB is a filterless, high-efficiency Class D audio power amplifier capable of delivering 2.5W per channel into a 4,Ѷ load with less than 10% total harmonic distortion plus noise (THD+N). It operates from a single supply voltage ranging from 2.4V to 5.5V, making it suitable for mobile and portable communication devices. The amplifier features a low noise PWM architecture that eliminates the need for an output filter, thereby reducing external component count and simplifying design. With a typical efficiency of 85% at 3.6V when driving an 8,Ѷ speaker at 500mW, the LM4674 also includes pin-selectable gain options and independent left/right shutdown control for power savings. Additional features include output short circuit protection and superior click and pop suppression during power-up and shutdown. The device is available in compact micro SMD and LLP packages, making it suitable for space-constrained applications.
