MAX5413EUD

Overview

The MAX5413EUD is a dual linear taper digital potentiometer from the MAX5413/MAX5414/MAX5415 family, manufactured by Analog Devices Inc./Maxim Integrated. It features two independent 3-terminal potentiometers with 256 tap points and a nominal resistance of 10kΩ. The device operates on a single supply voltage ranging from +2.7V to +5.5V with an ultra-low supply current of 0.1µA. It utilizes a 3-wire serial interface compatible with SPI™ for wiper control. Key electrical characteristics include a 35ppm/°C end-to-end temperature coefficient, glitchless switching between taps, and a power-on reset (POR) function that sets the wiper to midscale upon power-up.

Feature Summary

• Dual 3-terminal potentiometers with 256 tap positions in a 14-pin TSSOP package
• Ultra-low 0.1µA supply current and operation from +2.7V to +5.5V
• Glitchless switching between resistor taps and power-on reset to midscale
• Low drift performance with 35ppm/°C end-to-end and 5ppm/°C ratiometric temperature coefficients

Applications

• Mechanical potentiometer replacement
• Low-drift programmable gain amplifier (PGA)
• Adjustable voltage reference circuits
• Programmable filters, delays, and time constants

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package and temperature range specifications. Ensure compliance with RoHS directives as indicated in official documentation before procurement.

Selection Notes

Select the MAX5413EUD when a 10kΩ resistance value is required; other variants offer 50kΩ or 100kΩ options. Ensure the application supports the extended industrial temperature range of -40°C to +85°C. Verify that the system logic levels are compatible with the 3-wire serial interface requirements.

Part Context

This component belongs to the MAX5413/MAX5414/MAX5415 family of dual, low-drift digital potentiometers. While sharing identical pinouts and functional interfaces, the family members differ primarily in their nominal end-to-end resistance values, allowing designers to choose the appropriate resistance range for specific circuit impedance requirements.

Replacement Considerations

Direct replacements within the same family include the MAX5414EUD (50kΩ) and MAX5415EUD (100kΩ), provided the resistance value adjustment is acceptable for the circuit design.
