It communicates over an SPI interface, which means the wiper position is set by a simple serial write — no external DAC or op-amp needed for a programmable voltage divider or adjustable reference. The 10-uMAX/uSOP package (3.00 mm body width) fits tight mixed-signal layouts where two independent pots are needed without doubling the footprint. ## SPI interface and volatile memory — design constraints at a glance The wiper setting is volatile, so on power-up the wiper returns to its default mid-scale position. Plan for a hardware reset or a software write in the init routine. ## Lifecycle and sourcing — no obsolescence headache here The MAX5405EUB+ carries an Active product status and is ROHS3 compliant. There is no NRND flag, no last-time-buy notice, and no announced end-of-life. That means it can be specified into new designs today without planning for a future substitution.","metaTitle":"MAX5405EUB+ Digital Potentiometer, 100kΩ, 256 Taps, SPI","metaDescription":"MAX5405EUB+ dual 100kΩ digital pot with 256 taps, SPI interface, ±25% tolerance, 35ppm/°C tempco.

Pin-compatible siblings in the same family include the MAX5406 (dual 50kΩ) and MAX5407 (dual 10kΩ) — same footprint, same SPI interface, same supply range, just different resistance values. If your BOM needs a different resistance, one of those may drop in without a layout change."},{"question":"What is the MAX5405EUB+'s listed taper?","answer":"The taper is Linear. That means the wiper resistance changes linearly with the digital code — no logarithmic curve. It is the right choice for voltage dividers, programmable references, and gain-setting resistors; not for audio volume control where an audio-taper (log) pot is preferred."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX5405EUB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX5405EUB when reusing this data.
