The TAS2560YFFR from Texas Instruments is a mono Class D audio amplifier delivering 5W into a 4Ω load from a single 1.65V–1.95V supply. Packaged in a 30-DSBGA, it's built for space-constrained, battery-powered audio paths — think portable speakers, smart home voice assistants, or IoT endpoints where board real estate is tight and efficiency matters. The integrated depop circuitry suppresses turn-on clicks, and the short-circuit and thermal protection reduce the need for external clamp diodes or supervisory ICs.
Supply and output — what the numbers mean for your BOM
The 1.65V–1.95V supply range is narrow but deliberate: it lets the amplifier run directly off a 1.8V rail common in low-power SoCs.
Temperature grade and environment
Rated for -40°C to 85°C ambient, this part covers industrial and outdoor IoT applications — think smart speakers on a factory floor, outdoor voice paging, or battery-powered sensors that see seasonal temperature swings. It is not specified for automotive under-hood environments (no AEC-Q100 in the record) and the 85°C ceiling rules out engine-bay or cabin-in-summer deployments. For a panel-mount audio output in a PLC cabinet or a weatherproof enclosure, the range is adequate.
