Each of the two channels draws 36 µA supply current, so the total quiescent draw for both amplifiers is 72 µA — a figure that keeps the part viable in battery-powered sensor interfaces and portable instrumentation where the op-amp must run continuously. ## Rail-to-rail output and drive capability The output swings rail-to-rail and can source or sink 55 mA per channel. That drive current is enough to charge the input capacitance of a downstream ADC sample-and-hold or to drive a moderate resistive load directly, without an external buffer stage. ## Package, footprint, and procurement posture Housed in a 10-UFQFN (0.55 mm max seated height) with a 1.4x1.8 mm body, the part demands a fine-pitch PCB layout. Analog Devices lists the MAX9638AVB+T as active in production and ROHS3 compliant. It is offered in Tape & Reel (TR) and Cut Tape (CT) options for volume or prototype procurement.","metaTitle":"MAX9638AVB+T CMOS op-amp, 1.5 MHz, dual, 10-UTQFN","metaDescription":"MAX9638AVB+T dual CMOS op-amp from Analog Devices: 1.5 MHz GBW, 0.9 V/µs slew rate, rail-to-rail output, 36 µA supply per channel, 10-UTQFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"0.9V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"CMOS","Package / Case":"10-UFQFN","lifecycle_stage":"eol_hot","Current - Supply":"36µA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"0.1 pA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"1.5 MHz","Voltage - Input Offset":"300 µV","Supplier Device Package":"10-UTQFN (1.4x1.8)","Current - Output / Channel":"55 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.1 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.44","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.44000","currency":"USD"},{"qty":10,"price":"$2.19500","currency":"USD"},{"qty":25,"price":"$2.07040","currency":"USD"},{"qty":100,"price":"$1.76410","currency":"USD"},{"qty":250,"price":"$1.65640","currency":"USD"},{"qty":500,"price":"$1.44936","currency":"USD"},{"qty":1000,"price":"$1.20089","currency":"USD"},{"qty":2500,"price":"$1.11807","currency":"USD"},{"qty":5000,"price":"$1.07666","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/43907cf51e5c3f0629b4a6cfc89acf30.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What package does MAX9638AVB+T use and what is the footprint?","answer":"It comes in a 10-UFQFN package (10-UTQFN supplier device package) with a 1.4x1.8 mm body."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX9638AVBT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX9638AVBT when reusing this data.
