MAX5483EUD+T

Overview

The MAX5483EUD+T is a 10-bit, nonvolatile, linear-taper digital potentiometer functioning as a variable resistor. It features a 10kΩ end-to-end resistance with 1024 tap positions and an internal EEPROM for power-on wiper recall. The device supports a pin-selectable 3-wire SPI-compatible serial interface or up/down digital interface, operating on a single +2.7V to +5.25V supply or ±2.5V dual supplies. It offers a nominal temperature coefficient of 35ppm/°C end-to-end and 5ppm/°C ratiometric, with a maximum standby current of 1µA.

Feature Summary

• 1024 Tap Positions: 10-bit resolution provides precise programmable resistance control.
• Nonvolatile Memory: Internal EEPROM stores wiper position for initialization during power-up.
• Flexible Interface: Pin-selectable 3-wire SPI-compatible serial interface or up/down digital interface.
• Low Power Consumption: 1µA (max) standby supply current; 400µA (max) during NV memory write.

Applications

• Mechanical Potentiometer Replacement
• Low-Drift Programmable Gain Amplifiers
• LCD Contrast Adjustment
• Pressure Sensors
• Gain and Offset Adjustment

Procurement Notes

Verify the component is the lead-free/RoHS-compliant version indicated by the '+' suffix in the part number. Confirm the package type matches the design requirements, as this specific model utilizes a 14-pin TSSOP package. Ensure the ordering suffix corresponds to the correct tape-and-reel quantity if applicable, though standard retail units may vary.

Selection Notes

Select the MAX5483EUD+T when a 10kΩ variable resistor configuration is required. Choose this over the MAX5481 if lower resistance is needed, or the MAX5484/MAX5482 if 50kΩ is preferred. Ensure the application requires a 2-terminal variable resistor rather than a 3-terminal voltage divider. Verify that the 10-bit resolution and nonvolatile storage meet the system's calibration needs.

Part Context

This component belongs to the MAX5481–MAX5484 family of 10-bit, nonvolatile, linear-taper digital potentiometers manufactured by Analog Devices / Maxim Integrated. The MAX5483 specifically denotes the 10kΩ variable resistor variant within this series, sharing core architectural features such as the EEPROM and dual-interface capabilities with its siblings.

Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX5481EUD+ (10kΩ voltage divider), MAX5482EUD+ (50kΩ voltage divider), and MAX5484EUD+ (50kΩ variable resistor). Ensure the replacement matches the required terminal configuration (variable resistor vs. voltage divider) and resistance value.
