Overview
The MAX5387MAUD+ 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 support up to eight devices on a common bus. The wipers default to the midscale position upon power-on.
Feature Summary
- Dual 256-Tap Linear Taper Positions
- Single +2.6V to +5.5V Supply Operation
- Low < 1μA Quiescent Supply Current
- I²C-Compatible Interface with Address Inputs
- -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 part number. Ensure proper handling procedures are followed due to surface-mount packaging requirements.
Selection Notes
Select the MAX5387MAUD+ when a 50kΩ end-to-end resistance is required. Compare against MAX5387LAUD+ (10kΩ) and MAX5387NAUD+ (100kΩ) based on circuit impedance needs. Verify that the volatile memory architecture aligns with system power-loss requirements.
Part Context
This component belongs to the MAX5387 series of dual digital potentiometers. It shares functional similarities with other Maxim Integrated digital potentiometer families but is distinct in its specific I²C interface implementation and automotive-grade temperature rating.
Replacement Considerations
Direct replacements include MAX5387LAUD+ and MAX5387NAUD+ if resistance values differ. Cross-reference with MAX5487EUD for nonvolatile alternatives, noting interface differences.
