SGM2820 3W Low EMI Class-D Audio Power Amplifier with Auto-Recovering Short-Circuit Protection GENERAL DESCRIPTION The SGM2820 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. When powered with 5V supply voltage, the SGM2820 is capable of delivering 3W into a 4Ω load or 1.7W into an 8Ω load, with 10% THD+N. As a Class-D audio amplifier, the SGM2820 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 SGM2820 over typical Class-D audio power amplifiers is that it generates much less EMI emissions, thus greatly simplifying the system design for portable applications.
