It runs on a 0.9V to 1.8V supply, so it fits battery-powered gear where the core rail sits at 1.2V or 1.5V. The mono output handles a stereo headphone signal internally. ## Package and temperature fit for field swaps Housed in a 12-UCSP measuring 2.02x1.54mm — that is a tiny BGA-style package with no leads. Swapping it on site means hot air and a steady hand; not a socketed part you pop in from a field kit. Rated for -40°C to +85°C ambient, so it handles outdoor telecom or industrial sensor heads without a heater. ## Lifecycle and compliance reality Note the RoHS status: non-compliant. If your assembly line is RoHS-exempt or you hold a stock of tin-lead solder, this part works. For lead-free reflow, look at the lead-free variant in the same family.","metaTitle":"MAX9721CEBC-T Analog Devices Class AB Headphone Amp, 25mW","metaDescription":"MAX9721CEBC-T Class AB headphone amplifier from Analog Devices DirectDrive series. 25mW mono output into 16Ω, 0.9V-1.8V supply, -40°C to +85°C.","metaKeywords":null},"attributes":{"series":"DirectDrive®","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Type":"Class AB","Series":"DirectDrive®","Package":"Bulk","Output Type":"1-Channel (Mono) with Stereo Headphones","Mounting Type":"Surface Mount","Package / Case":"12-WFBGA, CSPBGA","lifecycle_stage":"eol_hot","Voltage - Supply":"0.9V ~ 1.8V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"12-UCSP (2.02x1.54)","Max Output Power x Channels @ Load":"25mW x 1 @ 16Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.07","stockQuantity":0,"priceTiers":[{"qty":281,"price":"$1.07000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2f4dbc5915d59d2503526084dd001b76.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX9721CEBC-T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX9721CEBC-T when reusing this data.
