The LM48312 is a single supply, high efficiency, mono, 2.6W, filterless switching audio amplifier. The LM48312 features National’s Enhanced Emissions Suppression (E 2S) system, that features a unique patented ultra low EMI, spread spectrum, PWM architecture, that significantly reduces RF emissions while preserving audio quality and efficiency. The E 2S system improves battery life, reduces external component count, board area consumption, and system cost, simplifying design.
The LM48312 is designed to meet the demands of portable multimedia devices. Operating from a single 5V supply, the device is capable of delivering 2.6W of continuous output power to a 4Ω load with less than 10% THD+N
