MAX5471EZT+T

Overview

The MAX5471EZT+T is a single-channel, non-volatile digital potentiometer manufactured by Analog Devices under the Maxim Integrated brand. It features a 32-tap linear taper resistance element with a nominal value of 10 kOhms and a temperature coefficient of 35 PPM/C. The device operates on a single supply voltage ranging from 2.7 V to 5.25 V, consuming a maximum operating current of 400 uA. It utilizes a 3-wire serial interface for control and is housed in a compact SOT-23-6 surface-mount package. The operational temperature range spans from -40°C to +85°C, ensuring reliability in industrial environments.

Feature Summary

• Non-volatile memory retains wiper position upon power loss
• 3-wire serial interface for simplified connectivity
• Linear taper resistance characteristic
• Low power consumption with 400 uA max operating current

Applications

• Battery-powered instrumentation systems
• Portable consumer electronics requiring volume or gain adjustment
• Industrial process control calibration circuits
• Programmable filter frequency setting applications

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeits. Confirm RoHS compliance status via official datasheets. Check lifecycle status as obsolescence may affect long-term availability. Ensure packaging specifications match production requirements.

Selection Notes

Select this component when a single-channel, non-volatile digital potentiometer with 32 taps is required. Verify that the 10 kOhm resistance value fits the circuit design constraints. Ensure the 2.7 V to 5.25 V supply range aligns with system power rails. Consider the SOT-23-6 package size for PCB layout compatibility.

Part Context

This part belongs to the MAX5471 series of non-volatile digital potentiometers. It shares functional similarities with other Maxim digital potentiometers but is distinct in its specific resistance value, tap count, and interface type. The series is designed for applications requiring adjustable resistance without mechanical components.

Replacement Considerations

Direct replacements include other MAX5471 variants with different resistance values (e.g., MAX5471EUT+T for 10k) or pin-compatible alternatives from the same manufacturer. Cross-reference electrical parameters such as voltage range and interface protocol before substitution.
