MAX5496ETE+

Overview

The MAX5496ETE+ is a dual, nonvolatile, linear-taper digital potentiometer featuring 10-bit (1024-tap) resolution. It functions as two independent variable resistors with end-to-end resistance values of 10kΩ and a temperature coefficient of 35ppm/°C. The device utilizes an internal EEPROM to store wiper positions for initialization upon power-up. It operates on a single supply voltage ranging from +2.7V to +5.25V or dual supplies of ±2.5V. Communication is handled via a 3-wire SPI-compatible serial interface supporting data rates up to 7MHz. The component is housed in a space-saving 16-pin TQFN package measuring 5mm x 5mm x 0.8mm.

Feature Summary

• Dual variable resistor configuration with 1024 tap points
• Nonvolatile memory retains wiper position during power loss
• 3-wire SPI-compatible serial interface with 7MHz clock rate
• Low standby current consumption of 1.5µA maximum

Applications

• Gain and offset adjustment circuits
• LCD contrast adjustment systems
• Pressure sensor signal conditioning
• Mechanical potentiometer replacement

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and temperature range specifications. Ensure compatibility with existing PCB footprints for the 16-pin TQFN-EP package before procurement. Confirm that the 10kΩ resistance value aligns with circuit design requirements.

Selection Notes

Select this model when a dual variable resistor topology is required rather than a programmable voltage divider. The MAX5496 variant provides access only to the wiper and low terminals for each channel. Verify that the 10kΩ end-to-end resistance meets the impedance constraints of the target application compared to the 50kΩ alternative.

Part Context

This component belongs to the MAX5494–MAX5499 family of 10-bit digital potentiometers manufactured by Analog Devices / Maxim Integrated. The MAX5496 specifically denotes the dual variable resistor configuration within this series, distinguishing it from voltage divider variants like the MAX5494.

Replacement Considerations

Direct functional substitutes within the same family include the MAX5497, which offers identical architecture but with 50kΩ end-to-end resistance.
