It uses a parallel interface to set the wiper position, and the wiper resistance is 500Ω typical. The part runs on a single 5V supply or dual ±5V rails, which makes it handy for bipolar signal chains without extra level shifting. It comes in an 8-uMAX/uSOP surface-mount package and operates over the -40°C to +85°C industrial temperature range. ## Supply voltage and what it means for the circuit The supply range of 5V or ±5V is the headline flexibility here. In a single-supply system, the wiper swings from ground to VDD. With ±5V, the wiper can swing through a bipolar range, useful for trimming offset in op-amp stages or setting thresholds in comparator circuits that reference mid-rail. The 4 taps give you only four discrete positions, so this is a coarse adjuster — think gain step selection or calibration trim, not fine volume control. ## Package and mounting — field-swap reality The 8-uMAX/uSOP package is a standard 3mm-wide MSOP-8 footprint. It is surface-mount, so no socket — you need a hot-air station or a fine-tip iron to swap it on site. ## Lifecycle and sourcing The MAX5420BEUA+ is listed as Active with ROHS3 compliance.","metaTitle":"MAX5420BEUA+ Digital Potentiometer, 15kΩ, 4-Tap, Linear","metaDescription":"MAX5420BEUA+ digital pot from Analog Devices: 15kΩ, 4 taps, linear taper, parallel interface, 5V/±5V supply, -40°C to +85°C, 8-uMAX.
