MAX5417META+

Overview

The MAX5417META+ is a single-channel, nonvolatile digital potentiometer featuring 256 tap positions and a nominal end-to-end resistance of 50kΩ. It utilizes a fast-mode I²C-compatible serial interface for wiper control and retains position data via internal EEPROM upon power loss. The device operates on a single supply voltage ranging from +2.7V to +5.25V with a typical standby current of 500nA. Packaged in an 8-pin TDFN (3mm x 3mm) format, it supports an extended operating temperature range of -40°C to +85°C.

Feature Summary

Nonvolatile memory stores wiper position for power-on recall
Fast-mode I²C-compatible serial interface supporting up to 400kbps
Linear taper with 256 tap points and ±0.5 LSB INL/DNL in voltage-divider mode
Low standby supply current of 500nA (typical)

Applications

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

Procurement Notes

Verify the specific factory-preset I²C address associated with the 'M' suffix before integration. Confirm that the 3mm x 3mm TDFN-EP package land pattern matches the design footprint. Ensure the system bus pull-up resistors are selected appropriately for the required SDA/SCL rise times.

Selection Notes

Select this component when a 50kΩ resistance value is required; the MAX5418 offers 100kΩ and the MAX5419 provides 200kΩ. The 'M' suffix dictates a specific default I²C slave address distinct from 'L', 'N', or 'P' variants. Verify that the 256-tap resolution meets the application's precision requirements compared to lower-resolution alternatives.

Part Context

This part belongs to the MAX5417/MAX5418/MAX5419 family of 256-tap, nonvolatile digital potentiometers. While sharing identical pinouts and interfaces, the family differentiates by nominal resistance values: 50kΩ for the MAX5417, 100kΩ for the MAX5418, and 200kΩ for the MAX5419.
