MAX5483ETE+T

Overview

The MAX5483ETE+T is a 10-bit, nonvolatile, linear-taper digital potentiometer manufactured by Analog Devices/Maxim Integrated. It functions as a variable resistor with a nominal end-to-end resistance of 10kΩ and 1024 tap positions. The device features an internal EEPROM for power-on recall of the wiper position. It supports a pin-selectable 3-wire SPI-compatible serial interface or an up/down digital interface, operating on a single supply from +2.7V to +5.25V or dual supplies of ±2.5V. The component is housed in a 16-pin TQFN package and operates within an extended temperature range of -40°C to +85°C.

Feature Summary

• 10-bit resolution providing 1024 distinct tap positions for precise resistance adjustment
• Nonvolatile EEPROM memory retains wiper position during power-off for automatic initialization
• Pin-selectable interface allowing configuration between 3-wire SPI-compatible serial mode and up/down digital mode
• Low standby current consumption of 1µA (max) and low ratiometric temperature coefficient of 5ppm/°C

Applications

• Mechanical potentiometer replacement in space-constrained designs
• Low-drift programmable gain amplifiers requiring stable voltage division
• Liquid crystal display (LCD) contrast adjustment circuits
• Pressure sensor signal conditioning and calibration
• Gain and offset adjustment in precision analog front-ends

Procurement Notes

Verify the specific ordering suffix 'E' corresponds to the TQFN-EP-16 package and the '+T' indicates tape-and-reel packaging. Confirm that the component is lead-free and RoHS compliant as indicated by the '+' suffix. Ensure the source documentation matches the MAX5481-MAX5484 datasheet for accurate electrical specifications regarding the 10kΩ variant.

Selection Notes

Select the MAX5483ETE+T when a 10kΩ variable resistor configuration is required rather than a voltage divider. Choose this model over the MAX5481 if the specific 10kΩ end-to-end resistance is needed. Verify that the application requires the 16-pin TQFN form factor. Consider the MAX5484 if a 50kΩ resistance value is preferred instead.

Part Context

This component belongs to the MAX5481–MAX5484 family of 10-bit nonvolatile digital potentiometers. The MAX5483 specifically denotes the 10kΩ variable resistor variant within this series. It shares architectural similarities with the MAX5481 (10kΩ voltage divider), MAX5482 (50kΩ voltage divider), and MAX5484 (50kΩ variable resistor).
