It uses a parallel interface for wiper position control and operates from a single 5V supply or dual ±5V rails. The volatile memory means the wiper setting resets to the midscale position at power-up, which suits calibration and trim applications where the initial condition is known. Packaged in a compact 10-uMAX/uSOP surface-mount package, it is rated for the industrial temperature range of -40°C to 85°C, making it appropriate for factory automation, instrumentation, and power-supply trimming in benign or conditioned environments. ## Key ratings and what they mean for the BOM The 15kΩ resistance is the full-scale value between the high and low terminals; the wiper resistance is typically 500Ω. ## Lifecycle and sourcing posture The MAX5421BEUB+ carries an Active product status with ROHS3 compliance.","metaTitle":"MAX5421BEUB+ Digital Potentiometer, 15kΩ, 4-Tap, Linear","metaDescription":"MAX5421BEUB+ digital potentiometer from Analog Devices. 15kΩ resistance, 4 taps, linear taper, parallel interface, 5V supply, -40 to 85°C.
