MAX5484EUD+T

Overview

The MAX5484EUD+T is a 10-bit, nonvolatile, linear-taper digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It functions as a variable resistor with an end-to-end resistance of 50kΩ and 1024 tap positions. The device features an internal EEPROM for power-on wiper recall and supports a pin-selectable 3-wire SPI-compatible serial interface or up/down digital interface. Operating on a single supply from +2.7V to +5.25V or dual ±2.5V supplies, it draws a maximum standby current of 1µA. The component is housed in a 14-pin TSSOP package and operates within an extended temperature range of -40°C to +85°C.

Feature Summary

• 10-bit resolution providing 1024 distinct tap positions
• Nonvolatile EEPROM memory retains wiper position during power loss
• Pin-selectable 3-wire SPI-compatible or Up/Down digital control interface
• Low standby current consumption of 1µA (max)
• End-to-end resistance of 50kΩ with 35ppm/°C temperature coefficient

Applications

• Mechanical potentiometer replacement
• Low-drift programmable gain amplifiers
• LCD contrast adjustment
• Pressure sensor signal conditioning
• Gain and offset adjustment circuits

Procurement Notes

Verify the presence of the '+' suffix to confirm lead-free and RoHS compliance. Confirm the 'EUD' designation indicates the 14-pin TSSOP package variant. Ensure the 'T' suffix matches the required reel packaging format for surface-mount assembly processes.

Selection Notes

Select the MAX5484 specifically when a 50kΩ variable resistor configuration is required. Choose this model over the MAX5481 if higher end-to-end resistance is needed compared to the 10kΩ alternative. Verify that the application utilizes the Wiper-to-Low terminal connection appropriate for variable resistor operation rather than voltage-divider usage.

Part Context

This component belongs to the MAX5481–MAX5484 family of 10-bit nonvolatile digital potentiometers. While sharing identical control interfaces and memory architectures, the MAX5484 is distinguished by its 50kΩ end-to-end resistance and variable resistor topology. It complements the MAX5481 (10kΩ voltage divider) and MAX5482 (50kΩ voltage divider) within the same product line.
