MAX5484ETE+T

Overview

The MAX5484ETE+T is a 10-bit, nonvolatile, linear-taper digital potentiometer configured as a variable resistor. It provides an end-to-end resistance of 50kΩ with 1024 tap positions and operates on a single +2.7V to +5.25V supply or ±2.5V dual supplies. 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. It is housed in a 16-pin TQFN package and specified over the -40°C to +85°C temperature range.

Feature Summary

10-bit resolution with 1024 tap positions
Nonvolatile memory stores wiper position for initialization
Pin-selectable 3-wire SPI or Up/Down digital interface
50kΩ end-to-end resistance with 35ppm/°C temperature coefficient

Applications

Mechanical potentiometer replacement
Low-drift programmable gain amplifiers
LCD contrast adjustment
Pressure sensor signal conditioning

Procurement Notes

Verify the component is lead-free and RoHS-compliant based on the '+' suffix. Confirm the 'E' designation corresponds to the 16-pin TQFN package and '+T' indicates reel packaging. Ensure the source documentation matches the specific MAX5484 variant rather than the broader MAX5481-4 family datasheet.

Selection Notes

Select the MAX5484ETE+T when a 50kΩ variable resistor configuration is required. Choose this part over the MAX5483 if higher resistance is needed. Verify that the application requires the nonvolatile feature for power-up state retention. Ensure the system voltage falls within the 2.7V to 5.25V single-supply range.

Part Context

This component belongs to the MAX5481–MAX5484 family of 10-bit digital potentiometers. The MAX5484 specifically denotes the 50kΩ variable resistor version. It shares architectural similarities with the MAX5481 (10kΩ voltage divider) and MAX5482 (50kΩ voltage divider), differing primarily in terminal configuration and resistance value.
