MAX5388NAUB+T

Overview

The MAX5388NAUB+T is a dual, volatile, low-voltage linear taper digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It features two independent 256-tap potentiometers with an end-to-end resistance of 100kΩ. The device operates from a single +2.6V to +5.5V supply and includes one voltage-divider configured potentiometer and one variable-resistor configured potentiometer. It utilizes an SPI-compatible interface for wiper control and maintains a low quiescent supply current of less than 1μA. The component is specified over an extended temperature range of -40°C to +125°C.

Feature Summary

SPI-Compatible Interface
-40°C to +125°C 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 the MAX5388NAUB+T datasheet specifications against design requirements before integration. Confirm that the 100kΩ resistance value and volatile memory characteristics align with system needs. Ensure the SPI interface timing parameters are compatible with the host controller. Check package dimensions for the 10-pin µMAX footprint during PCB layout.

Selection Notes

Select the MAX5388NAUB+T when a dual digital potentiometer with high resistance (100kΩ) is required in a compact 10-pin µMAX package. This variant is suitable for applications needing one voltage divider and one variable resistor configuration. Consider the MAX5388MAUB+T or MAX5388LAUB+T if lower resistance values (50kΩ or 10kΩ) are preferred for different impedance matching or current handling requirements.

Part Context

The MAX5388NAUB+T belongs to the MAX5386/MAX5388 family of dual, 256-tap, volatile, low-voltage linear taper digital potentiometers. This family offers three end-to-end resistance options: 10kΩ, 50kΩ, and 100kΩ. The MAX5388 specifically provides mixed configurations, including one voltage-divider and one variable-resistor setup, distinguishing it from the MAX5386 which offers two voltage-divider configurations.
