The package is an 8-pin HVSSOP with an exposed pad. 700 mW into 8 Ω is a headphone-amp level, not a speaker-amp level. It'll drive a small speaker for beeps and voice prompts. ## Protection features — shutdown, short-circuit, thermal Built-in shutdown pin lets a microcontroller kill the amp when idle, saving battery draw. Short-circuit and thermal protection keep it from self-destructing if the output gets grounded or the board gets hot. Depop circuitry suppresses the turn-on thump that would otherwise hit the speaker.","metaTitle":"TPA721DGN Class AB Audio Amp, 700mW into 8Ω, 8-MSOP","metaDescription":"Texas Instruments TPA721DGN Class AB mono audio amplifier delivers 700mW into 8Ω. 2.5V-5.5V supply, -40°C to 85°C, 8-HVSSOP.

That's the rated maximum output power for the mono channel."},{"question":"Does TPA721DGN require a heatsink?","answer":"No external heatsink is needed if the PCB layout provides a solid thermal path through the exposed pad on the HVSSOP package. The pad is the primary heat-dissipation path."},{"question":"What is the closest pin-compatible alternative to TPA721DGN?","answer":"The TPA721DGN is part of TI's TPA721 family. The TPA721DGN is the industrial-temperature, HVSSOP-packaged variant. The standard TPA721 (without the 'DGN' suffix) is in a different package (SOIC or MSOP without exposed pad). For a direct pin-compatible drop-in, stick with the TPA721DGN — the exposed pad footprint is specific to the DGN package code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPA721DGN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPA721DGN when reusing this data.
