MAX5418META

Overview

The MAX5418META is a single-channel, nonvolatile digital potentiometer IC manufactured by Analog Devices (Maxim Integrated). It features a total resistance of 100 kOhms with a linear taper and 256 tap positions for precise resistance adjustment. The device operates on a serial interface and includes EEPROM storage to retain the wiper setting during power loss. It supports a supply voltage range from 2.7 V to 5.25 V and functions within an industrial temperature range of -40°C to +85°C. Packaged in a TDFN-8 EP surface-mount format, it offers low power consumption suitable for embedded systems.

Feature Summary

• Nonvolatile memory retains wiper position after power cycle
• 256-tap resolution with 100 kOhm total resistance
• Serial I²C-compatible interface for control
• Industrial temperature range (-40°C to +85°C)

Applications

• Programmable gain amplifiers
• Voltage reference trimming
• Sensor bias adjustment

Procurement Notes

Verify the specific suffix 'META' against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage levels and I²C addressing requirements before integration.

Selection Notes

Select this component when nonvolatile resistance settings are required without external memory. The 100 kOhm value suits high-impedance signal paths. Confirm that the TDFN-8 EP package fits the PCB layout constraints and thermal management needs.

Part Context

Part of the MAX541x family, which includes MAX5417 (10 kOhm) and MAX5419 (100 kOhm variants with different specs). This series provides a standardized interface and form factor for digital potentiometry applications across various resistance values.

Replacement Considerations

MAX5418PETA+ is a verified alternative in the same series with identical electrical characteristics but may differ in packaging or reel configuration. Verify pinout and software register compatibility before substitution.
