The document describes the features and characteristics of the TPA3001D1 20W mono class-D audio power amplifier. It features high efficiency, short circuit protection, third-generation modulation technique, and low supply current.
The TPA3001D1 is a 20‑W mono bridge‑tied load (BTL) Class‑D audio power amplifier that delivers high efficiency without the need for a heat sink. It operates from a 3.6 V to 18 V supply and can drive 4‑Ω or 8‑Ω speakers, offering gain settings of 12, 18, 23.6, and 36 dB.
The device is supplied in a thermally enhanced 24‑pin TSSOP (PWP) package with a PowerPAD™ for improved heat dissipation. Detailed terminal functions, recommended operating conditions, and absolute‑maximum ratings are provided, along with typical performance graphs for efficiency, THD+N, and supply current.
