It delivers 25 mW per channel into a 16 Ω load from a single supply rail that runs as low as 0.9 V and up to 1.8 V. ## Supply voltage and output power — what they mean for your BOM The 0.9 V to 1.8 V supply range is the headline constraint. The 25 mW into 16 Ω is enough for moderate listening levels with most consumer headphones. ## Lifecycle and sourcing reality The MAX9721AETC carries an Active lifecycle status from Maxim (now part of Analog Devices). No last-time-buy notice or NRND flag is on record.","metaTitle":"MAX9721AETC DirectDrive® Class AB Headphone Amplifier, 25mW","metaDescription":"MAX9721AETC is a Maxim Integrated DirectDrive® Class AB stereo headphone amplifier delivering 25mW per channel into 16Ω.","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-WQFN Exposed Pad","lifecycle_stage":"eol_hot","Voltage - Supply":"0.9V ~ 1.8V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"12-TQFN (4x4)","Max Output Power x Channels @ Load":"25mW x 1 @ 16Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.87","stockQuantity":0,"priceTiers":[{"qty":344,"price":"$0.87000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2f4dbc5915d59d2503526084dd001b76.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output power of MAX9721AETC?","answer":"It delivers 25 mW per channel into a 16 Ω load.
