Supply range is 2.9 V to 3.63 V, typical for a digital-input Class D amp running from a 3.3 V system rail; the integrated short-circuit protection latches off the output on a hard fault, so the downstream speaker and PCB traces see a controlled shutdown rather than continuous DC. ## Package and thermal interface Supplied in a 48-lead HTSSOP with an exposed thermal pad — the same footprint as the 48-TFSOP but the pad is the primary heat path. The pad must be soldered to a copper plane on the PCB; without it the 56 W output into 4 Ω drives the junction above the 85 °C ambient ceiling within seconds. Surface-mount only. The tube packaging is typical for prototype and low-volume builds; reel options exist for production but the order code specifies tube. Confirm the tube quantity against your line requirement before committing the BOM. ## Lifecycle and compliance status The ROHS3 declaration covers the full substance restriction list (lead, mercury, cadmium, hexavalent chromium, PBBs, PBDEs, plus the four phthalates).","metaTitle":"TAS5756MDCA Class D amp, 56W mono / 28W stereo, HTSSOP-48","metaDescription":"Texas Instruments TAS5756MDCA PurePath Class D amp: 56W x 1 @ 4Ω or 28W x 2 @ 4Ω, 2.9-3.63V supply, -25 to 85°C, Active, ROHS3.
