Product details

700 mW mono into 8 Ω — the output rating that defines the load

The TPA301D is a Texas Instruments Class AB audio amplifier delivering 700 mW into an 8 Ω load from a single channel. That output level suits it for driving a small speaker in battery-powered or line-powered audio paths — think portable radios, intercoms, alarm annunciators, or simple voice prompts in industrial panels.

Built-in protection: short-circuit, thermal, and shutdown

Short-circuit and thermal protection are on-die, so a speaker lead short or a stalled airflow condition won't cascade into a board-level failure. The shutdown pin lets a microcontroller or GPIO hold the amplifier in a low-power idle when no audio is needed — useful for battery-conscious designs where the amp is the largest quiescent draw.

The ROHS3 compliance clears RoHS-directed markets without exemption paperwork.

Frequently asked questions

Does TPA301D have thermal protection and shutdown?

Yes — the TPA301D includes on-die short-circuit protection, thermal protection, and a shutdown pin. The shutdown pin allows a logic-level signal to disable the amplifier for power saving.
