Operating temperature covers -40°C to 85°C, placing it in the industrial band — suitable for outdoor telecom, automotive cabin, or factory-floor audio signalling. ## Protection features and pop suppression On-chip short-circuit and thermal protection prevent the output stage from failing under a miswired headphone jack or sustained clipping. Depop circuitry suppresses the turn-on/turn-off thump that would otherwise couple into the headphones — no external mute FET or series resistor needed. A shutdown pin lets the system pull the amplifier into low-power idle when audio is not active, saving battery in portable designs. ## 8-HVSSOP package with exposed thermal pad Surface-mount assembly with standard reflow profile; the exposed pad adds a low-thermal-resistance path to the board, so the 70 mW output does not push the die past the 85°C ambient ceiling. ROHS3 compliant, with no exemptions that would block EU or California market entry.","metaTitle":"TPA122DGN Class AB Stereo Headphone Amp, 70mW, 8-HVSSOP","metaDescription":"Texas Instruments TPA122DGN Class AB stereo headphone amplifier, 70mW x 2 into 8Ω, 2.5-5.5V supply, -40 to 85°C, active production, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Class AB","Package":"Tube","Features":"Depop, Short-Circuit and Thermal Protection, Shutdown","Output Type":"Headphones, 2-Channel (Stereo)","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"2.5V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-HVSSOP","Max Output Power x Channels @ Load":"70mW x 2 @ 8Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.99","priceTiers":[{"qty":1,"price":"$1.99000","currency":"USD"},{"qty":10,"price":"$1.78900","currency":"USD"},{"qty":25,"price":"$1.68800","currency":"USD"},{"qty":100,"price":"$1.43820","currency":"USD"},{"qty":250,"price":"$1.35044","currency":"USD"},{"qty":500,"price":"$1.18164","currency":"USD"},{"qty":1000,"price":"$0.97907","currency":"USD"},{"qty":2500,"price":"$0.95550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/975d594da5267d5b6dd62506935abf3f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPA122DGN/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPA122DGN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPA122DGN when reusing this data.
