Its 90 kHz gain-bandwidth product and 0.04 V/µs slew rate limit it to DC and low-frequency signals — think sensor conditioning, battery monitoring, or reference buffering, not audio or high-speed control loops. ## 14 µA supply current and 2 nA input bias — sizing for battery and high-impedance circuits Quiescent supply current is just 14 µA, making this op-amp a fit for always-on or battery-powered designs where every microamp matters. The 2 nA input bias current is low enough for most resistive sensor bridges and photodiode amplifiers without excessive voltage offset from source impedance. ## 2.5 mA output current — what it can and cannot drive Each channel can source or sink 2.5 mA. That drives the input of an ADC, a comparator, or a logic gate directly, but not a relay coil, a headphone, or a long cable. Plan on a buffer stage if the load impedance is below about 2 kΩ at 5 V supply.","metaTitle":"MAX4040EUK General Purpose Op-Amp, 90 kHz","metaDescription":"MAX4040EUK single general-purpose op-amp, 90 kHz GBW, 0.04 V/µs slew rate, rail-to-rail output, 2.4 V to 5.5 V supply, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Bulk","Slew Rate":"0.04V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Current - Supply":"14µA","Number of Circuits":"1","Current - Input Bias":"2 nA","Operating Temperature":"-40°C ~ 85°C","Gain Bandwidth Product":"90 kHz","Voltage - Input Offset":"250 µV","Supplier Device Package":"SOT-23-5","Current - Output / Channel":"2.5 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.4 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.42","stockQuantity":0,"priceTiers":[{"qty":211,"price":"$1.42000","currency":"USD"}]},"links":{"datasheetUrl":"https://rocelec.widen.net/view/pdf/7kcbj5x5qb/MAXMS12832-1.pdf?t.download=true&u=5oefqw","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX4040EUK rail-to-rail output?","answer":"Yes, the output type is rail-to-rail, allowing the output to swing close to both supply rails — useful when running from a low supply voltage where headroom is scarce."},{"question":"What is the closest pin-compatible alternative to MAX4040EUK?","answer":"The MAX4040EUK is a single op-amp in SOT-23-5. Within the same Maxim family, the MAX4041 offers a higher slew rate and wider bandwidth if the signal frequency demands it, but the pinout and supply range are the same. For a direct second source, check the Microchip MCP6001 in SOT-23-5 — same pinout, 1 MHz GBW, rail-to-rail I/O, but supply current is higher at 100 µA. Verify the pinout against your layout before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX4040EUK","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX4040EUK when reusing this data.
