A dedicated shutdown pin lets the system microcontroller pull the amplifier into a low-power idle state, saving battery draw when audio is not needed. The 8-SOIC package has a 1.27 mm pitch with visible lead tips — easy to hand-solder or hot-air rework without a stencil. No exposed thermal pad means the part does not need a ground-plane slug for cooling; the copper traces under the body are enough for the 1.1 W dissipation at room temperature.","metaTitle":"Texas Instruments TPA4861D Class AB Audio Amp, 1.1W, 8-SOIC","metaDescription":"Texas Instruments TPA4861D Class AB mono audio amplifier, 1.1W into 8Ω, 2.7-5.5V supply, -40 to +85°C, 8-SOIC.
