It delivers 50W per channel into a 4Ω load from a single supply rail spanning 4.5V to 26V. Built-in short-circuit and thermal protection plus a dedicated mute pin simplify the system-level protection scheme. Differential inputs reject ground-loop noise common in multi-channel installations. The 32-HTSSOP package with exposed pad draws heat to the PCB copper plane — no external heatsink needed for typical music playback at moderate levels. ## Supply voltage and temperature — fit for your environment","metaTitle":"TPA3116D2DADR TI Class-D Amp 50W x 2 @ 4Ω 32-HTSSOP","metaDescription":"Texas Instruments TPA3116D2DADR Class-D stereo amplifier, 50W x 2 @ 4Ω. 4.5V-26V supply, -40°C to 85°C.
