The TPA3116D2DADR is a Class-D stereo amplifier from TI's SpeakerGuard™ series. 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.
