MAX5419META+

Overview

The MAX5419META+ 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 200kΩ 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 EEPROM for power-on recall of the wiper position. Packaged in a compact 3mm x 3mm 8-pin TDFN format, it supports extended industrial operating temperatures from -40°C to +85°C.

Feature Summary

• Nonvolatile memory retains wiper position across power cycles
• I²C serial interface with four factory-preset address options
• 200kΩ nominal resistance with ±0.5 LSB INL/DNL accuracy
• Low standby current of 500nA typical

Applications

• Mechanical potentiometer replacement
• Low-drift programmable-gain amplifiers
• Liquid-crystal display contrast control

Procurement Notes

Verify the specific ordering suffix META+ corresponds to the required I²C slave address configuration (010101A) and lead-free RoHS compliance status before procurement. Confirm that the 200kΩ resistance value aligns with the target circuit impedance requirements.

Selection Notes

Select this component when a high-resistance digital potentiometer is required for precision applications. Ensure the system design accommodates the 200kΩ end-to-end resistance and the specific I²C address assigned by the META suffix to prevent bus conflicts.

Part Context

This part belongs to the MAX541x family of 256-tap digital potentiometers. While sharing identical architecture and pinouts with the MAX5417 (50kΩ) and MAX5418 (100kΩ), the MAX5419 variant specifically offers a 200kΩ resistance range suitable for high-impedance signal chains.

Replacement Considerations

Direct functional replacements within the same package include the MAX5417META+ and MAX5418META+, provided the lower resistance values are acceptable for the application.
