The Class D switching stage keeps efficiency high, so the 42-DSBGA package doesn't need a heatsink for most use cases. Supply voltage is tight at 1.65 V to 1.95 V — this part runs off the same 1.8 V rail as the SoC or DSP, no separate audio power rail needed. ## Package rework reality: 42-DSBGA The 42-DSBGA is a 0.4 mm pitch ball-grid array — that's a fine-pitch BGA, not a hand-solderable package. Reflow requires a stencil and a hot-air or convection oven profile. The thermal pad is on the bottom center, so the board needs a via array under the package to pull heat into the inner copper layers. The package is ROHS3 compliant, so the solder balls are lead-free SAC alloy. ## Built-in protection reduces external BOM Short-circuit and thermal protection are integrated on-die. That means no external current-sense resistor, no comparator, and no thermal cutoff PTC on the output. The protection folds back or shuts down the output stage before the die temperature exceeds the absolute maximum — the amplifier recovers when the fault clears.","metaTitle":"TAS2555YZR Class D Audio Amp, 5.7 W Mono, 42-DSBGA","metaDescription":"Texas Instruments TAS2555YZR Class D audio amplifier, 5.7 W mono into 4 Ω, 1.65-1.95 V supply, -40°C to 85°C, 42-DSBGA.
