1.5W mono Class D in a 2.2 mm² footprint
The TPA2014D1YZHT is a Texas Instruments Class D audio amplifier delivering 1.5 W continuous into an 8 Ω load from a single mono channel — enough output for a portable speaker, voice prompt, or alarm tone in a package that fits a 2.24 × 2.16 mm DSBGA land pattern.
Protection and shutdown features
Differential inputs reject common-mode noise on the audio line, and the integrated short-circuit and thermal protection circuits latch the output off before the die exceeds its safe junction temperature — no external protection clamping diodes needed. A dedicated shutdown pin pulls the quiescent current below 1 µA, letting a host processor gate the amplifier power between audio bursts without a discrete load switch.
DSBGA assembly and supply posture
The 16-bump DSBGA (2.24 × 2.16 mm) requires a solder-paste stencil matched to the 0.5 mm pitch and a reflow profile that stays within the package's moisture sensitivity level — the bump array is the only electrical interface, so board-level inspection needs X-ray or side-scope verification of the solder joints.
