Typical applications include portable speakers, headphone amplifiers, intercoms, and line-driver stages in battery-powered or low-voltage equipment where a clean linear output is preferred over a Class D switching stage. The 8-SOIC package (0.154\" body width, 3.90 mm) is a standard surface-mount footprint. It reworks cleanly under hot air — low thermal mass, no hidden pads.","metaTitle":"TPA311D Class AB Audio Amp, 700 mW Mono, 8-SOIC","metaDescription":"TPA311D Class AB mono amplifier delivers 700 mW into 8 Ω.
