On-chip features include depop, mute, short-circuit and thermal protection, and shutdown control. ## Output power and load matching The 30W mono rating into 8Ω suits a single-speaker soundbar or subwoofer channel; the 15W stereo into 4Ω drives a pair of bookshelf speakers in a multi-media system. The supply voltage directly affects output swing — a 26V rail gives the full 30W, while a 12V rail will deliver proportionally less. Check your speaker impedance and supply headroom before locking the BOM. ## Supply range and thermal design The 10V to 26V supply range lets you run from a standard 12V automotive battery or a 24V industrial rail without a separate regulator. Without that thermal path, the thermal protection will trip at lower output levels.","metaTitle":"TPA3121D2PWPR Class-D Audio Amp, 30W Mono / 15W Stereo","metaDescription":"TPA3121D2PWPR Class-D audio amplifier IC from TI. 30W mono into 8Ω or 15W stereo into 4Ω. 10V-26V supply, -40 to 85°C.
