Housed in a 48-PowerTQFP (48-HTQFP 7x7) package, it mounts directly on a PCB without a separate heatsink for most applications, because Class D efficiency keeps conduction losses low. The supply range spans 10V to 26V, so it can run off a common 12V or 24V rail used in industrial panel audio or point-of-sale terminals. ## Protection and control features for reliable field operation On-chip short-circuit and thermal protection prevent the amplifier from failing into a DC rail fault or sustained overload — a common failure mode in unmonitored installations. The mute and shutdown pins let a system controller or GPIO assert silent start-up and low-power idle, cutting quiescent draw when audio is not needed. Differential inputs reject ground-loop noise between the audio source and the amplifier — useful when the source and amp sit on different boards or power supplies. ## Temperature grade and deployment context Rated for -40°C to 85°C ambient, the TPA3100D2PHP suits outdoor kiosks, digital signage, or equipment enclosures that see seasonal temperature swings. ## Lifecycle and sourcing posture Texas Instruments lists the TPA3100D2PHP as Active with no last-time-buy or obsolescence notice — the part remains in standard production and is available through authorized distribution. ROHS3 compliant, so it passes EU material restrictions without an exemption — no lead-free process change needed at the assembly house. Sourced and quoted to order against your BOM quantity; availability and current pricing confirmed at RFQ time.","metaTitle":"Texas Instruments TPA3100D2PHP Class D Audio Amplifier","metaDescription":"Texas Instruments TPA3100D2PHP Class D stereo amplifier, 21.8W x 2 into 8Ω, 48-HTQFP, -40°C to 85°C.
