Class G topology uses a dual-supply rail to reduce power dissipation at lower output levels — the amplifier switches between rails only when the signal demands it, so battery-powered devices see less thermal loss than a fixed Class AB stage. ## Feature set for portable audio integration On-chip features include differential inputs, I²C-controlled volume, mute, depop circuitry, and short-circuit and thermal protection. The depop circuit suppresses turn-on/turn-off clicks without external timing capacitors — a common pain point in headphone amplifier designs. The output drives stereo headphones (2-channel) directly. The 16-DSBGA package (1.56 mm × 1.56 mm) suits space-constrained PCBs in smartphones, tablets, and portable audio modules.","metaTitle":"TPA6140A2YFFT Class G Stereo Headphone Amp, 32mW, DSBGA","metaDescription":"Texas Instruments TPA6140A2YFFT Class G stereo headphone amplifier, 32mW x 2 into 32Ω, I²C volume control, 2.5-5.5V supply, -40 to 85°C, Active, ROHS3.","metaKeywords":null},"attributes":{"series":"DirectPath™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Class G","Series":"DirectPath™","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Depop, Differential Inputs, I²C, Mute, Short-Circuit and Thermal Protection, Shutdown, Volume Control","Output Type":"Headphones, 2-Channel (Stereo)","Mounting Type":"Surface Mount","Package / Case":"16-UFBGA, DSBGA","lifecycle_stage":"eol_hot","Voltage - Supply":"2.5V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"16-DSBGA (1.56x1.56)","Max Output Power x Channels @ Load":"32mW x 2 @ 32Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.77","priceTiers":[{"qty":1,"price":"$2.77000","currency":"USD"},{"qty":10,"price":"$2.48600","currency":"USD"},{"qty":25,"price":"$2.34520","currency":"USD"},{"qty":100,"price":"$1.99820","currency":"USD"},{"qty":250,"price":"$1.87620","currency":"USD"},{"qty":500,"price":"$1.64168","currency":"USD"},{"qty":1250,"price":"$1.36025","currency":"USD"},{"qty":2500,"price":"$1.32750","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0d05aa6a47a2eaeac4e9a242d1c233e2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPA6140A2YFFT/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does Texas Instruments provide for TPA6140A2YFFT?","answer":"The part is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPA6140A2YFFT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPA6140A2YFFT when reusing this data.
