MAX5434NEZT

Overview

The MAX5434NEZT+ is a single-channel, nonvolatile digital potentiometer manufactured by Analog Devices Inc. (Maxim Integrated). It features a 50 kΩ resistance value with a linear taper and offers 32 tap positions for precise adjustment. The device operates on a supply voltage ranging from 2.7 V to 5.25 V and draws a typical operating current of 2 µA. It utilizes an I²C-compatible serial interface for control. The component is housed in a compact SOT-23-6 surface-mount package and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

• Nonvolatile memory retains wiper position upon power loss
• I²C-compatible serial interface for simplified connectivity
• Low power consumption with 2 µA operating current
• Compact SOT-23-6 surface-mount packaging

Applications

• Battery-powered portable devices requiring adjustable gain or offset
• Consumer electronics needing volume or tone control adjustments
• Industrial systems utilizing I²C buses for calibration settings

Procurement Notes

Verify the complete part number suffix, such as '+', which indicates RoHS compliance, when sourcing. Confirm availability status through authorized distributors, as stock levels fluctuate. Ensure the selected variant matches the required package type and temperature rating for the specific application environment.

Selection Notes

Select this component when a single-channel digital potentiometer with nonvolatile storage is required. The 50 kΩ resistance and 32 taps provide sufficient resolution for many analog control applications. Verify that the system's I²C bus speed and voltage levels are compatible with the device's 2.7 V to 5.25 V operating range.

Part Context

This part belongs to the MAX5434 series of nonvolatile digital potentiometers. It serves as a solid-state replacement for mechanical potentiometers in circuits where space is limited or remote adjustment capabilities are necessary. The series is designed for applications requiring reliable, long-term resistance setting without continuous power.

Replacement Considerations

Check for direct replacements within the MAX5434 family, such as variants with different resistance values or package options. Ensure any substitute maintains the same nonvolatile memory feature and I²C interface compatibility.
