MAX5427EUA

Overview

The MAX5427EUA is a discontinued single-channel digital potentiometer IC manufactured by Analog Devices Inc./Maxim Integrated. It features a 100 kOhm resistance value with a linear taper and 32 taps for precise adjustment. The device utilizes a non-volatile memory architecture to retain the wiper setting without power, controlled via a serial 2-wire interface. Designed for surface-mount applications in TDFN-8 EP packages, it operates within a temperature range of -40°C to +85°C.

Feature Summary

Non-volatile memory retains wiper position after power loss
Single channel with 32-tap linear taper configuration
Serial 2-wire digital interface for control
100 kOhm nominal resistance with 25% tolerance

Part Context

This component belongs to the MAX5427 series of one-time programmable digital potentiometers. It is distinct from volatile or multi-channel variants within the broader Maxim portfolio. The 'EUA' suffix indicates an industrial temperature grade (-40°C to +85°C) and specific packaging. As a legacy part, it has been superseded by newer generations in the company's product line.

Replacement Considerations

The datasheet lists the MAX5427EUA+ as a direct replacement. This variant typically denotes compliance with RoHS standards compared to the older leaded version. Verification of pin compatibility and electrical specifications against the current design requirements is necessary before substitution.
