It delivers 100 mW per channel into 16 Ω loads from a 1.8 V to 4.5 V supply, covering single-cell Li-ion and two-cell alkaline battery rails. The depop circuit suppresses startup and shutdown transients, and integrated short-circuit and thermal protection guard against output faults. For new designs, this part is a safe BOM line — no near-term replacement planning needed. The DirectPath™ family shares a common pinout across several output-power grades, so a future spin to a higher-power sibling (if needed) is a straightforward PCB layout change.","metaTitle":"TPA4411RTJT Class AB Stereo Headphone Amp, 100mW, 20-QFN","metaDescription":"TI TPA4411RTJT Class AB stereo headphone amplifier, 100mW x 2 into 16Ω, 1.8V-4.5V supply, -40°C to 85°C, 20-QFN.

The difference is packaging and reel quantity: the RTJT suffix typically denotes a smaller reel (250 units) while the RTJR suffix denotes a larger reel (3000 units). Both are the same functional part."},{"question":"What is the output power of TPA4411RTJT into 32 ohms?","answer":"The datasheet specifies 100 mW per channel into 16 Ω. Output power into 32 Ω will be lower due to the higher load impedance; the exact figure depends on supply voltage and THD+N target, but expect roughly 50-60 mW per channel at 3.3 V supply."},{"question":"Can TPA4411RTJT be used in battery-powered devices?","answer":"Yes. The 1.8 V to 4.5 V supply range covers single-cell Li-ion (3.0-4.2 V) and two-cell alkaline (2.4-3.0 V) battery chemistries. The low quiescent current and shutdown feature make it suitable for portable audio gear."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPA4411RTJT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPA4411RTJT when reusing this data.
