It runs on a single 5 V supply for both the analog and digital sections, so you don't need a separate AVDD/DVDD pair or a charge pump. The external reference (REF) sets the full-scale output, which means the same BOM can serve multiple output spans by swapping the reference voltage. ## R-2R ladder — monotonic by design The R-2R resistor-ladder architecture gives inherently monotonic transfer: every increase in digital code produces a corresponding increase in analog output, with no missing codes. Because the output is unbuffered, the DAC's output impedance is the R-2R ladder's own (~10 kΩ typical). That means it drives a high-impedance load (like an op-amp input or a comparator) directly, but for a 50 Ω or 75 Ω terminated line you need an external buffer. The trade-off is lower power and no buffer-induced offset error. ## SPI interface and package fit The SPI data interface uses a standard 3-wire (SCLK, DIN, CS) protocol. Multiple MAX5441 devices can share the same bus in a daisy-chain or individual chip-select topology — useful for multi-channel analog output cards where you want to minimise the number of digital isolator channels. The exposed pad on the underside is not present — this is a standard 8-lead MSOP with no thermal slug, so the power dissipation is limited to about 0.5 W at 85°C ambient without airflow. That means it's safe to qualify into a new design today and expect multi-year production availability. ROHS3 compliant (exemption-free per EU 2015/863), so it ships without any of the restricted substances and doesn't trigger the 0.1% threshold reporting that ROHS2 exemptions can cause.","metaTitle":"MAX5441BEUA+ 16-bit DAC, SPI, 1µs settling, 8-uMAX","metaDescription":"Analog Devices MAX5441BEUA+ 16-bit voltage-output DAC, R-2R architecture, ±0.5 LSB INL, 1µs settling, SPI interface, -40 to +85°C, 8-uMAX.

This sets the maximum update rate: at 1 µs settle time, you can update the DAC at roughly 1 MSPS (mega-sample per second) assuming the SPI clock can keep up. For a servo loop with a 10 kHz bandwidth, the DAC settles in 1% of the loop period — plenty of margin."},{"question":"Can I use the MAX5441BEUA+ with a 3.3 V digital supply?","answer":"No — the digital supply (DVDD) is specified at 5 V, same as the analog supply. The part does not have a separate low-voltage digital rail. If your microcontroller runs at 3.3 V, you need a level translator on the SPI lines or a 5 V-tolerant MCU."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX5441BEUA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX5441BEUA when reusing this data.
