Supply voltage flexibility — 10V to 30V single supply or ±5V to ±15V dual supply — means the part sits comfortably in both single-rail industrial systems and split-supply analog signal chains. The 128-tap resolution delivers 256 distinct wiper positions across the 100kΩ end-to-end resistance, giving roughly 781 Ω per step, though the 900 Ω wiper resistance sets the minimum end-to-end value. ## Active lifecycle and compliance Analog Devices lists the MAX5439EUD+ as Active and ROHS3 Compliant. The tube packaging is the standard factory delivery for this TSSOP-14; reel or tape-and-reel options, if needed, are confirmed at RFQ.","metaTitle":"MAX5439EUD+ 100kΩ 128-Tap SPI Digital Potentiometer","metaDescription":"Active Analog Devices MAX5439EUD+ 100kΩ SPI digital potentiometer, 128 taps, linear taper, 14-TSSOP.
