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.","metaTitle":"TPA301D Class AB Audio Amp, 700mW Mono, 8-SOIC","metaDescription":"Texas Instruments TPA301D Class AB audio amplifier: 700mW into 8Ω mono, 2.5V-5.5V supply, -40°C to 85°C, short-circuit & thermal protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Class AB","Package":"Tube","Features":"Short-Circuit and Thermal Protection, Shutdown","Output Type":"1-Channel (Mono)","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.5V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Max Output Power x Channels @ Load":"700mW x 1 @ 8Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.47","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.47000","currency":"USD"},{"qty":10,"price":"$1.31600","currency":"USD"},{"qty":25,"price":"$1.24960","currency":"USD"},{"qty":100,"price":"$1.02640","currency":"USD"},{"qty":250,"price":"$0.95944","currency":"USD"},{"qty":500,"price":"$0.84790","currency":"USD"},{"qty":1000,"price":"$0.66939","currency":"USD"},{"qty":2500,"price":"$0.63150","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/052005ba798fa6673af19042c69e3264.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does TPA301D have thermal protection and shutdown?","answer":"Yes — the TPA301D includes on-die short-circuit protection, thermal protection, and a shutdown pin.
