Overview
The MAX5450EUB+ is a dual digital potentiometer from Analog Devices/Maxim Integrated, housed in a 10-pin µMAX package. It functions as two independent 2-terminal variable resistors with 256 tap positions controlled via an up/down interface. Operating on a single supply of +2.7V to +5.5V, it draws ultra-low supply current of 0.1µA at VDD = 2.7V. The device features a power-on reset that sets the wiper to midscale (position 127) and ensures glitchless switching between resistor taps. It offers a 10kΩ end-to-end resistance with a temperature coefficient of 35ppm/°C.
Feature Summary
- Dual 2-terminal variable resistors with 256 digitally-controlled wiper positions
- Ultra-low supply current of 0.1µA at VDD = 2.7V
- Glitchless switching between resistor taps using up/down interface
- Power-on reset sets wiper to midscale position (127)
Applications
- Mechanical potentiometer replacement
- Low-drift programmable-gain amplifier (PGA)
- Volume control
- LCD screen adjustment
- Adjustable voltage references
Procurement Notes
Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices. Ensure storage conditions maintain device integrity prior to assembly. Validate pinout compatibility with existing PCB footprints before procurement.
Selection Notes
Select this model for applications requiring dual variable resistors in a compact 10-pin package. Choose based on the required 10kΩ resistance value; other variants offer 50kΩ or 100kΩ options. Consider the 14-pin TSSOP package if three-terminal potentiometer functionality is needed instead of two-terminal variable resistance.
Part Context
This component belongs to the MAX5450–MAX5455 family of dual digital potentiometers. While sharing similar architecture and interface protocols, specific part numbers differ by resistance value and terminal configuration. The MAX5450 specifically denotes the 10kΩ variant configured as two-variable resistors within the 10-pin µMAX form factor.
Replacement Considerations
Direct substitutes include MAX5452EUB+ (50kΩ) and MAX5454EUB+ (100kΩ) for identical packaging but different resistance values. For three-terminal potentiometer functionality, consider MAX5451EUD+, MAX5453EUD+, or MAX5455EUD+ in the 14-pin TSSOP package.
