MAX5472EZT

Overview

The MAX5472EZT+T is a single-channel digital potentiometer IC featuring 32 nonvolatile taps and linear taper characteristics. It operates within a supply voltage range of 2.7 V to 5.25 V, with a typical operating current of 400 uA at 5 V. The device incorporates a 100 kOhm resistive element with a temperature coefficient of 35 PPM/C. Control is managed via a serial 3-wire interface. Packaged in a TSOT-23-6 surface-mount format, it supports an industrial temperature range from -40°C to +85°C.

Feature Summary

• Nonvolatile memory retains wiper position upon power loss
• Serial 3-wire digital interface for control
• Single potentiometer with 32 linear taps
• Low power consumption (400 uA typical)

Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Sensor calibration circuits

Procurement Notes

Verify the complete part number including suffixes such as '+T' or 'E' against official Analog Devices documentation. Confirm RoHS compliance status and specific package variants. Check distributor availability as stock levels may vary by region.

Selection Notes

Select this component when a single-channel, nonvolatile digital potentiometer with a 100 kOhm resistance value is required. Ensure the design utilizes a 3-wire serial interface rather than up/down control. Verify that the 32-tap resolution meets the application's precision requirements.

Part Context

This component belongs to the MAX5472 series of nonvolatile digital potentiometers. It is manufactured by Analog Devices under the Maxim Integrated brand. The series offers various resistance values and interface options, with this specific model focusing on 100 kOhm linear taper performance.

Replacement Considerations

Check for direct cross-references within the MAX547x family, such as MAX5473 or MAX5474, noting differences in resistance values and control interfaces. Verify pin compatibility before substitution.
