Overview
The MAX5387NAUD+T is a dual, 256-tap, volatile, low-voltage linear taper digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It features an end-to-end resistance of 100kΩ and operates from a single +2.6V to +5.5V power supply. The device provides a low 35ppm/ºC temperature coefficient and consumes less than 1μA in standby mode. It utilizes an I2C-compatible interface for control and is specified over the automotive -40ºC to +125ºC temperature range. The component is housed in a 14-pin TSSOP package.
Feature Summary
- Dual, 256-Tap Linear Taper Positions
- Single +2.6V to +5.5V Supply Operation
- Low < 1μA Quiescent Supply Current
- I2C-Compatible Interface
Applications
- Low-Voltage Battery Applications
- Portable Electronics
- Mechanical Potentiometer Replacement
- Offset and Gain Control
- Adjustable Voltage References/Linear Regulators
Procurement Notes
Verify that the ordering suffix 'AUD' corresponds to the 100kΩ resistance value and the 14-pin TSSOP package configuration. Confirm RoHS compliance status as indicated by the '+' designation. Ensure the specific tape-and-reel packaging requirements are met for automated assembly processes.
Selection Notes
Select this variant when a 100kΩ end-to-end resistance is required. Verify that the system voltage falls within the 2.6V to 5.5V operating range. Consider the volatile memory characteristic, which requires wiper position restoration after power loss. Ensure the I2C bus supports the maximum SCL frequency of 400 kHz.
Part Context
This component belongs to the MAX5387 family of dual digital potentiometers. Other variants include the MAX5387LAUD+ (10kΩ) and MAX5387MAUD+ (50kΩ). All share identical pinouts, interfaces, and electrical characteristics except for the end-to-end resistance value.
Replacement Considerations
Direct replacements within the same family include MAX5387LAUD+ and MAX5387MAUD+. These parts maintain functional compatibility but differ in resistance values. Cross-family replacements require verification of interface protocols and voltage specifications.
FAQ
What is the default wiper position upon power-on?
Both wipers A and B power up at the midscale position, corresponding to code 80H.
How many devices can share a common I2C bus?
Up to eight devices can share a common bus using the three address inputs (A0, A1, and A2).
Is the memory non-volatile?
No, the MAX5387 features volatile memory. Wiper positions are lost upon power removal.
