Settling time is 25 µs typical, fast enough for closed-loop control loops or waveform generation in the low-kHz range, and the SPI data interface keeps the digital pin count to four lines (CS, SCLK, DIN, and the serial-data output for daisy-chaining). INL and DNL are both specified at ±1 LSB maximum — monotonicity is guaranteed over the full operating range, so the output code never decreases for an increasing digital input, which matters for servo loops and ramp generators. ## Dual-supply operation with flexible reference The part runs on split analog (±5 V) and digital (5 V) supplies, with the option to use either an external reference or the internal 2.5 V reference — the internal reference simplifies the BOM when absolute accuracy is not critical, while the external reference allows a ratiometric or precision voltage source. Operating temperature range is -40°C to +85°C, covering industrial and most commercial environments without a temperature-grade upcharge. ## 14-SOIC package — reel or cut-tape options Housed in a standard 14-SOIC (3.90 mm body width) surface-mount package, the MAX531BESD+T is available in both Tape & Reel and Cut Tape options — the reel format suits automated pick-and-place lines with high-volume feeders, while cut tape works for prototype or low-quantity builds. ## RoHS3 compliance — no exemption paperwork needed The part is RoHS3 compliant (2015/863/EU), meaning it meets the latest EU restriction levels for lead, mercury, cadmium, and the four phthalates — no additional compliance documentation or exemption justification is required for EU-market shipments.","metaTitle":"MAX531BESD+T 12-Bit DAC, Voltage Out, 14-SOIC, Active","metaDescription":"Analog Devices MAX531BESD+T 12-bit voltage-buffered DAC, R-2R architecture, SPI interface, 25µs settling, ±1 LSB INL/DNL.
