MAX5414EUD+T

Overview

The MAX5414EUD+T is a dual linear taper digital potentiometer from Analog Devices/Maxim Integrated, housed in a 14-pin TSSOP package. It operates on a single supply voltage ranging from +2.7V to +5.5V with an ultra-low supply current of 0.1µA. Each device contains two independent 3-terminal potentiometers featuring 256 tap positions controlled via a 3-wire SPI-compatible serial interface. The end-to-end resistance is nominally 50kΩ with a temperature coefficient of 35ppm/°C and a ratiometric coefficient of 5ppm/°C. A power-on reset feature sets the wiper to midscale upon startup.

Feature Summary

• Dual 3-terminal potentiometers with 256 tap positions
• Ultra-low 0.1µA supply current
• +2.7V to +5.5V single-supply operation
• Glitchless switching between resistor taps

Applications

• Mechanical Potentiometer Replacement
• Low-Drift Programmable Gain Amplifier (PGA)
• Adjustable Voltage Reference

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific ordering suffixes that may affect packaging or temperature range specifications before finalizing procurement.

Selection Notes

Select the MAX5414EUD+T when a 50kΩ nominal resistance is required. Compare against MAX5413EUD+T for 10kΩ applications and MAX5415EUD+T for 100kΩ requirements within the same family. Ensure the design supports the 3-wire serial interface timing constraints.

Part Context

This component belongs to the MAX5413/MAX5414/MAX5415 family of dual, low-drift digital potentiometers. All variants share identical pinouts, interfaces, and features, differing only in their nominal end-to-end resistance values: 10kΩ, 50kΩ, and 100kΩ respectively.

Replacement Considerations

Direct functional substitutes within the same series include MAX5413EUD+T and MAX5415EUD+T, provided the resistance value difference is acceptable for the circuit design.
