MAX5413EUD+

Overview

The MAX5413EUD+ is a dual linear taper digital potentiometer from the MAX5413/MAX5414/MAX5415 family, manufactured by Analog Devices/Maxim Integrated. It features two independent 3-terminal potentiometers with 256 tap positions and an end-to-end 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 SPI-compatible serial interface for wiper control and includes glitchless switching between resistor taps. A power-on reset (POR) circuit sets the wiper to the midscale position at power-up.

Feature Summary

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

Applications

• Mechanical Potentiometer Replacement
• Low-Drift Programmable Gain Amplifier (PGA)
• Volume Control
• LCD Screen Adjustment
• Adjustable Voltage Reference

Procurement Notes

Verify the 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 the product documentation. Cross-reference the datasheet revision to ensure compatibility with design requirements.

Selection Notes

Select the MAX5413EUD+ when a 10kΩ resistance value is required; other variants offer 50kΩ or 100kΩ options. Consider the 8-bit resolution and 256 tap positions for fine-tuning applications. Evaluate the low drift characteristics for precision circuits requiring stable resistance over temperature variations. Ensure the system supports the 3-wire serial interface protocol for proper communication.

Part Context

The MAX5413EUD+ belongs to the MAX5413/MAX5414/MAX5415 family of dual digital potentiometers. These devices are designed to replace mechanical potentiometers in space-constrained applications. The family shares similar features but differs in nominal resistance values, allowing designers to choose the appropriate variant based on circuit impedance requirements.

Replacement Considerations

Direct replacements within the same family include the MAX5414EUD+ (50kΩ) and MAX5415EUD+ (100kΩ). Verify that the substitute part number matches the required resistance value and package type. Ensure compatibility with existing serial interface configurations and voltage supply levels.
