It communicates over an SPI interface and delivers an unbuffered voltage output, settling to within 1 LSB in 4 µs typical. The part operates from a single 2.5V to 5.5V supply — analog and digital share the same rail — making it a natural fit for battery-powered or 3.3V/5V systems where board space is tight. Housed in an 8-lead uMAX/uSOP package, it targets applications like programmable voltage references, digital trim pots, and low-speed closed-loop control in industrial or instrumentation settings. ## Supply range and logic compatibility — one rail to rule them Both the analog and digital supply pins share a common 2.5V to 5.5V range. That means a single 3.3V or 5V rail powers the entire DAC, and the SPI input thresholds track that rail. If your logic runs at 3.3V, the MAX550ACUA+ works directly — no level shifters needed. The 0°C to 70°C operating temperature covers commercial and most indoor industrial environments, but not extended or automotive ranges. ## Settling time and linearity — what the numbers mean for your calibration budget The 4 µs typical settling time sets the maximum update rate at roughly 250 kSPS for a full-scale step, though the unbuffered output means the load impedance directly affects the RC time constant. The integral nonlinearity is specified at ±0.9 LSB maximum — not a precision-grade converter, but adequate for 8-bit control loops and trim applications where the reference is external and can be chosen for drift performance. If you need better than 1 LSB absolute accuracy, budget for a calibration step at the system level. ## Package and handling — uMAX footprint notes The 8-uMAX/uSOP package (3.00 mm body width) is a common footprint shared with many Maxim small-outline parts. No moisture sensitivity level is stated, but standard MSL 1 handling is typical for this package family — still, bake before reflow if the bag seal is broken and the floor-life window is uncertain. ## Lifecycle and compliance — active and RoHS3 It is RoHS3 compliant, so it passes the material restrictions for EU and most global markets. For new designs, this part is a safe choice without obsolescence risk in the near term.","metaTitle":"MAX550ACUA+ Dual 8-Bit DAC, 4µs Settling, SPI, 8-uMAX","metaDescription":"MAX550ACUA+ dual 8-bit voltage-output DAC with R-2R architecture, 4µs typical settling time, SPI interface, 2.5V-5.5V supply, 8-uMAX package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Output Type":"Voltage - Unbuffered","Architecture":"R-2R","INL/DNL (LSB)":"-, ±0.9 (Max)","Mounting Type":"Surface Mount","Settling Time":"4µs (Typ)","Data Interface":"SPI","Number of Bits":"8","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Reference Type":"External","lifecycle_stage":"eol_hot","Differential Output":"No","Operating Temperature":"0°C ~ 70°C","Supplier Device Package":"8-uMAX/uSOP","Number of D/A Converters":"2","Voltage - Supply, Analog":"2.5V ~ 5.5V","Voltage - Supply, Digital":"2.5V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.86","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.86000","currency":"USD"},{"qty":10,"price":"$5.26400","currency":"USD"},{"qty":25,"price":"$4.97680","currency":"USD"},{"qty":100,"price":"$4.31320","currency":"USD"},{"qty":250,"price":"$4.09200","currency":"USD"},{"qty":500,"price":"$3.67176","currency":"USD"},{"qty":1000,"price":"$3.09666","currency":"USD"},{"qty":2500,"price":"$2.94183","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/73d9f1d6305443a913b5a93a4008bfc0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX550ACUA+ work with 3.3V logic?","answer":"Yes.
