The Texas Instruments TPA3101D2RGZT is a Class D stereo audio amplifier delivering 10W per channel into an 8Ω load. That 10W x 2 @ 8Ω rating makes it a fit for powered speakers, soundbars, automotive aftermarket head units, and industrial audio alert systems where you need clean audio from a 10V to 26V supply rail. The Class D topology keeps efficiency high — typically above 85% at full output — so the 48-VFQFN package with exposed pad can dissipate the heat without a bulky heatsink in many designs.
The 10V to 26V supply range covers common automotive battery voltages (12V nominal, 24V truck systems) and industrial 24V rails. Differential inputs, mute, and short-circuit/thermal protection are built in — the mute pin simplifies power-up pop suppression, and the protection suite means you don't need external clamp diodes on the output stage for most fault conditions.
Package and layout — the exposed pad is your thermal path
Housed in a 48-VFQFN with exposed pad, the TPA3101D2RGZT relies on the pad soldered to a PCB copper plane for thermal dissipation. The supplier device package is 48-VQFN (7x7 mm). Surface-mount only. For a 10W-per-channel Class D amp running from a 26V rail, the PCB layout should use a solid ground plane under the pad with multiple vias to inner-layer copper — the thermal pad is the primary heat path, not the package body.
