It operates from a 2.5V to 5.5V supply, making it suitable for single-cell Li-ion or 3.3V/5V rail designs in portable audio gear. ## I²C-controlled feature set Volume control, input multiplexer selection, and depop (click/pop suppression) are all managed over the I²C bus — no external pots or analog switches needed. Integrated short-circuit and thermal protection, plus a shutdown pin, simplify the system-level protection scheme. The 25-DSBGA package (0.4mm pitch typical for this class) requires careful PCB layout for thermal and signal integrity, but the small footprint saves board space in compact designs.","metaTitle":"TPA2051D3YFFT Texas Instruments Class D Amp, 2.9W","metaDescription":"Texas Instruments TPA2051D3YFFT Class D audio amp, 2.9W mono + 25mW stereo headphone, I2C control, 25-DSBGA, active production, ROHS3.
