Overview
The MAX5393MAUD+ is a dual digital potentiometer IC from Analog Devices/Maxim Integrated, housed in a 14-pin TSSOP package. It features two independent 256-tap linear taper potentiometers with an end-to-end resistance of 50kΩ and a tolerance of ±25%. Operating on a single supply voltage ranging from +1.7V to +5.5V, the device draws a quiescent current as low as 12μA at 1.7V. It utilizes a 3-wire SPI interface for control and includes an internal charge pump to maintain wiper resistance below 200Ω across the full voltage range. The unit operates within an automotive temperature range of -40°C to +125°C.
Feature Summary
- Dual 256-Tap Linear Taper Positions

Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Note that this specific part number may be subject to discontinuation; check current availability and lifecycle status before finalizing procurement plans.
Selection Notes
Select the MAX5393MAUD+ when a 50kΩ end-to-end resistance is required for dual-channel applications. Ensure the system supports a 1.7V to 5.5V supply range and utilizes an SPI interface. Consider the volatile memory type, which requires setting the wiper position upon power-up, unlike non-volatile alternatives.
Part Context
This component belongs to the MAX5393 series of dual digital potentiometers. Other variants in the series include the MAX5393LAUD+ (10kΩ) and MAX5393NAUD+ (100kΩ), all sharing the same 14-pin TSSOP package and functional architecture but differing in resistance values.
Replacement Considerations
Direct replacements within the same family include MAX5393LAUD+ and MAX5393NAUD+. Verify that the alternative part's resistance value matches the circuit requirements, as only the middle letter indicates the resistance tier.
FAQ
What is the wiper position after power-on?
The power-on reset (POR) circuitry sets both wipers to the midscale position (code 80h).
How does the device handle low supply voltages?
An internal charge pump ensures the maximum wiper resistance remains less than 200Ω even at supply voltages down to 1.7V.
What is the maximum clock frequency for the SPI interface?
The maximum SCLK frequency is 10 MHz.
