What this Class D amp delivers — and where it fits
The Texas Instruments TPA3110D2PWP is a Class D stereo audio amplifier rated for 15W per channel into an 8Ω load. That output level suits it for powered speakers, soundbars, automotive audio head units, and portable PA systems where battery or 12V rail efficiency matters. The SpeakerGuard™ series includes adjustable gain limiting and DC detection to keep the speaker cone from over-travel on a clipped signal — a practical safeguard for single-supply designs that don't have a dedicated protection controller. Supply range spans 8V to 26V.
15W x 2 into 8Ω is the rated output. The 8V minimum supply allows operation from a 12V battery at end-of-discharge. Differential inputs reject ground-loop noise common in multi-board audio chains. Short-circuit and thermal protection are built in — no external crowbar or over-temp sense needed. The Shutdown pin lets a microcontroller put the amp into low-power idle when no audio is present, saving battery in portable gear.
The 0.173-inch body width fits standard SOIC-28 footprints with a thermal land pattern. Surface-mount only; no through-hole variant exists.
