The Maxim Integrated MAX5400EKA+T is a single-channel, 50kΩ digital potentiometer with 256 wiper tap positions, controlled via an SPI interface. It belongs to the SOT-PoT™ family and comes in an 8-pin SOT-23 package — a footprint that fits tightly on sensor modules, handheld instruments, or any board where a mechanical trimmer needs replacement by a digitally set divider. The linear taper suits level-setting, gain adjustment, or bias calibration in analog signal chains.
