SGM2822 2.4W Low EMI Class-D Audio Power Amplifier with Auto-Recovering Short-Circuit Protection GENERAL DESCRIPTION FEATURES The SGM2822 is a high efficiency, low EMI, filterless, Class-D audio amplifier with auto-recovering short-circuit protection. It operates from 2.5V to 5.5V supply voltage for 8Ω load. When powered with 5.0V supply voltage, the SGM2822 is capable of delivering 1.7W into an 8Ω load, with 10% THD+N. As a Class-D audio amplifier, the SGM2822 features 88% efficiency and 70dB PSRR at 217Hz which make the device ideal for battery-powered high-quality audio applications. A key benefit of the SGM2822 over typical Class-D audio power amplifiers is that it generates much less EMI emissions, thus greatly simplifying the system design for portable applications.
