It communicates over a standard SPI data interface, making it a straightforward drop-in for any MCU with a spare SPI port. The 25 µs typical settling time means you can update the output at roughly 40 kHz without worrying about the previous value bleeding into the next — fine for set-point control in industrial loops, programmable voltage references, or sensor excitation. The ±1 LSB max INL and DNL guarantees monotonicity across codes, so you won't see non-monotonic glitches in servo or trim applications. Both the analog and digital supply rails run from a single 5 V supply, which keeps the power routing simple and lets you share a common 5 V rail with the rest of the analog front end. The industrial temperature range of -40°C to +85°C covers outdoor telecom cabinets, factory-floor PLCs, and engine-bay control modules without needing a separate temperature grade. ## Active lifecycle — no LTB clock ticking This is a straightforward BOM line — no shortage-driven redesign needed, no broker-only dependency. The part is ROHS3 compliant, which clears the environmental compliance gate for new designs going into EU or California-regulated markets. ## Package and footprint — 8-SOIC, tube delivery The device comes in an 8-pin SOIC package with a 0.154-inch body width and 3.90 mm nominal width, surface-mount. The supplier device package is listed as 8-SOIC. It ships in a Tube, which is typical for small-quantity prototyping and low-volume production runs — if you need tape-and-reel for pick-and-place, check the alternate ordering code (MAX538BESA+T). The standard SOIC-8 footprint is widely supported by assembly houses, and the pin pitch is the standard 1.27 mm.","metaTitle":"MAX538BESA+ 12-Bit DAC, SPI, Voltage-Output, 8-SOIC","metaDescription":"Maxim MAX538BESA+ 12-bit voltage-output DAC with SPI interface, ±1 LSB INL/DNL, 25µs settling, -40°C to +85°C, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Output Type":"Voltage - Buffered","Architecture":"R-2R","INL/DNL (LSB)":"±1 (Max), ±1 (Max)","Mounting Type":"Surface Mount","Settling Time":"25µs (Typ)","Data Interface":"SPI","Number of Bits":"12","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Reference Type":"External","lifecycle_stage":"eol_hot","Differential Output":"No","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"8-SOIC","Number of D/A Converters":"1","Voltage - Supply, Analog":"5V","Voltage - Supply, Digital":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$18.92","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$18.92000","currency":"USD"},{"qty":10,"price":"$17.38800","currency":"USD"},{"qty":25,"price":"$16.66720","currency":"USD"},{"qty":100,"price":"$14.68500","currency":"USD"},{"qty":250,"price":"$13.96424","currency":"USD"},{"qty":500,"price":"$13.06334","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/460a72ed9c4b6258c76a76373bc4adb3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the resolution of MAX538BESA+?","answer":"The MAX538BESA+ is a 12-bit DAC, providing 4096 discrete output levels from its buffered voltage output."},{"question":"Does MAX538BESA+ have an SPI interface?","answer":"Yes, the data interface is SPI, so it connects directly to the SPI bus of any microcontroller without glue logic."},{"question":"What is the output type of MAX538BESA+?","answer":"The output type is Voltage - Buffered, meaning the DAC output is a voltage signal with an internal buffer that can drive moderate loads directly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX538BESA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX538BESA when reusing this data.
