What this Class-D smart amp brings to the board
The TAS2564YBGR is a mono Class-D audio amplifier from Texas Instruments with an integrated DSP, rated for 7W continuous output into an 8Ω load from a single 1.8V supply rail. That 7W figure is the headline — it tells you this part drives a small speaker at moderate volume, typical for portable speakers, soundbars, or smart-home devices where board space is tight and the DSP handles EQ, limiting, and speaker protection in one package. The 1.65V–1.95V supply range means it runs off a regulated 1.8V core rail, not a battery or 5V bus — plan your power tree accordingly.
Temperature range and environment
Rated for -40°C to 85°C operating temperature, this amp is comfortable in consumer and industrial indoor environments — think smart speakers, conference-room audio, or home-theater subwoofers. Not rated for automotive or extended outdoor use beyond 85°C ambient.
