The Maxim Integrated MAX5389NAUD+ is a dual-channel, 256-tap digital potentiometer configured as a linear-taper potentiometer. Each of the two independent potentiometers presents a 100kΩ end-to-end resistance with a wiper resistance of 250Ω typical.
For volume production or long-term program commitments, qualifying a second source is always prudent — but the Active status means there is no forced replacement window.
The difference is the shipping medium: the MAX5389NAUD+ ships in a Tube, while the MAX5389NAUD+T ships in Tape & Reel. The electrical specifications, package (14-TSSOP), and temperature range are identical.
Yes, it is ROHS3 compliant.
The taper is Linear.
