The MAX5484EUD+T is a single-channel, 50kΩ digital potentiometer configured as a rheostat. It offers 1024 wiper tap positions. The non-volatile memory stores the wiper setting, so the part powers up at the last programmed position without host intervention.
The MAX5484EUD+T is an active, current-production part per the manufacturer. No end-of-life notices or last-time-buy windows are in effect.
Yes. The supply range includes 3.3V, and the SPI logic thresholds are compatible with 3.3V logic levels when powered from a 3.3V supply. No level shifting is required for 3.3V microcontrollers.
The MAX5484EUD+T has a linear taper. This means the wiper resistance changes linearly with the digital code, suitable for voltage dividers, gain-setting resistors, and calibration trimmers. It is not intended for audio volume control, which typically requires a logarithmic (audio) taper.
The MAX5481 (10kΩ), MAX5482 (50kΩ), and MAX5483 (100kΩ) are pin-compatible siblings in the same family, sharing the same 14-TSSOP package, 1024-tap resolution, non-volatile memory, and interface options. The MAX5484EUD+T is the 50kΩ variant. Check the specific resistance value needed for your application.
