The LM48511SQ/NOPB is a filterless mono class D Audio Power Amplifier with spread spectrum. This device integrates a boost converter with a high-efficiency class D audio power amplifier to provide 3W continuous power into a 8R speaker when operating from a 5V power supply. When operating from a 3 to 4V power supply, the LM48511 can be configured to drive 1 to 2.5W into a 8R load with less than 1% distortion (THD+N). The class D amplifier features a low-noise PWM architecture that eliminates the output filter, reducing external component count, board area consumption and simplifying design. A selectable spread spectrum modulation scheme suppresses RF emissions, further reducing the need for output filters. The switching regulator of the LM48511 is a current-mode boost converter operating at a fixed frequency of 1MHz.
● Selectable spread spectrum mode reduces EMI
