MAX5417NETA+T

Overview

The MAX5417NETA+T is a nonvolatile, linear-taper digital potentiometer featuring 256 tap positions and an I²C-compatible serial interface. It provides a nominal end-to-end resistance of 50kΩ with a temperature coefficient of 35ppm/°C. The device operates on a single supply voltage ranging from +2.7V to +5.25V and includes internal nonvolatile EEPROM for power-on wiper recall. Packaged in a compact 3mm x 3mm 8-pin TDFN format, it supports data rates up to 400kbps and maintains low static supply current.

Feature Summary

• Nonvolatile memory retains wiper position across power cycles
• I²C-compatible 2-wire serial interface with factory-set address
• 50kΩ nominal resistance with ±0.5 LSB INL/DNL accuracy
• Extended operating temperature range from -40°C to +85°C

Applications

• Mechanical potentiometer replacement
• Low-drift programmable-gain amplifier circuits
• Liquid-crystal display (LCD) contrast control

Procurement Notes

Verify the specific ordering suffix NETA corresponds to the required I²C slave address configuration before procurement. Confirm that the package type matches the PCB land pattern requirements for the 8-pin TDFN-EP footprint. Ensure the selected component meets the environmental specifications for the intended operating temperature range.

Selection Notes

Select this model when a 50kΩ resistance value is required alongside nonvolatile storage capabilities. Compare against MAX5418 or MAX5419 variants if higher resistance values of 100kΩ or 200kΩ are needed instead. Verify that the system bus voltage levels are compatible with the specified input high and low voltage thresholds for reliable communication.

Part Context

This component belongs to the MAX5417/MAX5418/MAX5419 family of digital potentiometers manufactured by Analog Devices Inc./Maxim Integrated. The NETA suffix designates a specific factory-programmed I²C address combination within the series. All members share identical pinouts and functional architectures while differing primarily in nominal resistance values.

Replacement Considerations

Direct replacements include other MAX5417 variants such as MAX5417LETA+ or MAX5417META+, provided the I²C address settings align with the system design constraints. Cross-family substitution requires verification of resistance tolerance and interface compatibility.
