Overview
The MAX5387NAUD+ is a dual, 256-tap, volatile, low-voltage linear taper digital potentiometer manufactured by Analog Devices / Maxim Integrated. It features an I2C-compatible interface and operates from a single +2.6V to +5.5V power supply. The device provides a low 35ppm/ºC end-to-end temperature coefficient and draws less than 1μA of quiescent supply current. It is specified over the automotive -40ºC to +125ºC temperature range and is available 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 component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free packaging details prior to procurement. Ensure proper handling procedures are followed for surface-mount components.
Selection Notes
Select the MAX5387NAUD+ variant specifically for applications requiring a 100kΩ end-to-end resistance value. Verify that the system voltage falls within the 2.6V to 5.5V operating range. Consider the volatile memory characteristic when designing power-loss recovery logic.
Part Context
This component belongs to the MAX5387 series of digital potentiometers. Other variants in this family include the MAX5387LAUD+ (10kΩ) and MAX5387MAUD+ (50kΩ), which share identical pinouts and functional specifications but differ in their end-to-end resistance values.
Replacement Considerations
Direct replacements within the same family include the MAX5387LAUD+ and MAX5387MAUD+. When substituting, verify that the required end-to-end resistance matches the application circuit constraints.
FAQ
What is the wiper position upon power-on?
Upon power-up, both wipers A and B automatically set to the midscale position, corresponding to code 80H.
How many devices can share a common I2C bus?
The device includes three address inputs (A0, A1, and A2), allowing up to eight MAX5387 units to be addressed individually on a single shared bus.
Does the MAX5387 support readback operations?
No, the MAX5387 does not support readback operations; it only supports write commands to update the wiper positions.
