The Class AB output stage means quiescent current is higher than a Class D equivalent, but the linearity avoids the switching noise and output filter that a Class D design requires. For battery-powered gear, the trade-off is standby time vs. audio fidelity. ## Lifecycle and compliance RoHS compliance is not claimed for this variant. If your BOM requires RoHS exemption documentation or a lead-free finish, confirm the date-code and plating before committing the line.","metaTitle":"MAX9719BETE Analog Devices Class AB Stereo Audio Amp","metaDescription":"Active-production Class AB stereo audio amplifier from Analog Devices. 1.4W x 2 at 4Ω, 2.7V–5.5V supply, –40°C to +85°C. 16-TQFN (4x4) package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Class AB","Package":"Bulk","Output Type":"2-Channel (Stereo)","Mounting Type":"Surface Mount","Package / Case":"16-WQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"2.7V ~ 5.5V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"16-TQFN (4x4)","Max Output Power x Channels @ Load":"1.4W x 2 @ 4Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.07","stockQuantity":0,"priceTiers":[{"qty":281,"price":"$1.07000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/496870a5158ede7b89ec5546915c20b8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MAX9719BETE in this Analog & Data Acquisition family?","answer":"The MAX9719BETE is a stereo Class AB amplifier in a 16-TQFN (4x4) package; a functional replacement would require evaluating other Analog Devices stereo audio amps with similar supply and output ratings, but pin compatibility is not guaranteed without a board layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX9719BETE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX9719BETE when reusing this data.
