With only four positions, this is a coarse adjustment part — think gain select or mode trim, not a precision voltage divider. The parallel interface sets the wiper position directly without a serial clock, so a few GPIO lines from a microcontroller or a DIP switch can control it. No protocol overhead, no shift-register delay — the wiper moves on the same bus cycle the data is written. Memory is volatile: the wiper resets to its default position (typically mid-scale) every time the supply is cycled. If the application needs to remember a calibration value across power-off, an external EEPROM or a non-volatile digital pot is required. Runs from a single 12 V to 15 V rail or from dual ±12 V to ±15 V supplies. The dual-supply option lets the wiper swing through ground, which is useful when the pot is used as a voltage divider in a bipolar signal chain — for example, trimming an op-amp offset that can be positive or negative. The 10-uMAX/uSOP package (3.00 mm × 3.00 mm body) is a compact surface-mount footprint that suits dense PCB layouts. Wiper resistance is 14 Ω typical — a small but non-zero series resistance that adds to the divider ratio. In a high-impedance load, the effect is negligible; in a low-impedance divider (e.g., setting a reference voltage for a 1 kΩ load), the 14 Ω wiper contributes a few percent of error. ## Active production, ROHS3, and sourcing posture ROHS3 compliant (no lead, no restricted substances beyond the standard exemptions), which means it ships into EU, UK, and global markets without a RoHS waiver.","metaTitle":"MAX5431AEUB+ Digital Potentiometer, 57kΩ, 4-Tap, Linear","metaDescription":"MAX5431AEUB+ digital potentiometer from Analog Devices: 57kΩ, 4 taps, linear taper, parallel interface, -40°C to 85°C, 10-uMAX.
