MAX5495ETE+

Overview

The MAX5495ETE+ is a dual, 10-bit (1024-tap), nonvolatile, linear-taper programmable voltage-divider IC. It features two independent channels with 50kΩ end-to-end resistance and a 3-wire SPI-compatible serial interface supporting data rates up to 7MHz. The device operates on a single supply from +2.7V to +5.25V or dual supplies of ±2.5V. Electrical characteristics include a 35ppm/°C end-to-end temperature coefficient and a 5ppm/°C ratiometric temperature coefficient. Standby current is 1.5µA maximum, while programming current reaches 400µA maximum. The unit is housed in a 16-pin TQFN package.

Feature Summary

• Dual 10-bit nonvolatile linear-taper programmable voltage-dividers

• 3-wire SPI-compatible serial interface with 7MHz clock rate
• Low standby current of 1.5µA maximum
• Extended temperature range specification (-40°C to +85°C)

Applications

• Gain and offset adjustment circuits
• LCD contrast adjustment
• Pressure sensor signal conditioning
• Low-drift programmable-gain amplifiers
• Mechanical potentiometer replacement

Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure that the ordering suffix corresponds to the specific package variant required for the design. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before integration into production systems.

Selection Notes

Select the MAX5495ETE+ when dual voltage-divider functionality with 50kΩ resistance is required. This model differs from the MAX5494 by its higher resistance value. Consider the 1024-tap resolution and nonvolatile memory retention capabilities for applications requiring precise digital control without mechanical wear. Verify that the 3-wire SPI interface aligns with the system's microcontroller or logic level requirements.

Part Context

This component belongs to the MAX5494–MAX5499 family of 10-bit digital potentiometers. While other members like the MAX5494 offer 10kΩ resistance, the MAX5495 specifically provides 50kΩ end-to-end resistance for both channels. All devices in this series share the same 16-pin TQFN footprint and nonvolatile memory architecture, differing primarily in terminal configuration and resistance values.

Replacement Considerations

The MAX5494ETE+ serves as a direct functional substitute within the same package if a lower 10kΩ resistance value is acceptable. Other family members such as the MAX5496 or MAX5498 may be considered if variable resistor configurations are preferred over voltage dividers. Verify that the replacement maintains the required 50kΩ resistance and dual-channel specification.
