Overview
The MAX5387MAUD+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 50kΩ 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 of quiescent current. It utilizes an I²C-compatible interface for control and includes three address inputs (A0, A1, A2) to allow up to eight devices on a common bus. Power-on resets the wipers to the midscale position.
Feature Summary
- Dual 256-Tap Linear Taper Digital Potentiometers
- I²C-Compatible Serial Interface with Address Inputs
- Low Quiescent Supply Current (< 1μA)
- -40ºC to +125ºC Operating Temperature Range
Applications
- Low-Voltage Battery Applications
- Portable Electronics
- Mechanical Potentiometer Replacement
- Offset and Gain Control
- Adjustable Voltage References/Linear Regulators
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated by the '+' suffix in the ordering information. Ensure proper handling procedures are followed during surface-mount assembly to maintain device reliability.
Selection Notes
Select this variant specifically for its 50kΩ end-to-end resistance value. Compare against MAX5387LAUD+T (10kΩ) and MAX5387NAUD+T (100kΩ) based on circuit impedance requirements. Verify that the volatile memory architecture aligns with system power-loss behavior expectations.
Part Context
This component belongs to the MAX5387 family of dual digital potentiometers. Related variants include the MAX5388 and MAX5393. Evaluation kits such as the MAX5387EVKIT+ are available for testing and development purposes.
Replacement Considerations
Direct substitutes within the same family include MAX5387LAUD+T and MAX5387NAUD+T, differing only in end-to-end resistance values. Cross-family replacements require verification of interface compatibility and pin configuration.
