Overview
The MAX5160LEUA+T is a low-power digital potentiometer in an 8-pin µMAX package. It provides 32 tap positions with a nominal end-to-end resistance of 50kΩ and a wiper resistance of 400Ω. The device operates on a single supply voltage ranging from +2.7V to +5.5V, drawing only 100nA of supply current. It features ±25% resistance tolerance, ±1LSB DNL, and ±0.5LSB INL. The component includes power-on reset functionality that sets the wiper to midscale (position 16) upon initialization.
Feature Summary

Procurement Notes
Verify the specific ordering suffix '+T' against official documentation to confirm tape-and-reel packaging requirements. Confirm the 'L' suffix indicates the 50kΩ resistance value as specified in the selector guide. Ensure compatibility with the 8-pin µMAX footprint during procurement planning.
Selection Notes
Select this part for applications requiring a 50kΩ variable resistor controlled via a serial interface. The 8-pin µMAX package is suitable for space-constrained designs. Consider the ±25% tolerance and 50ppm/°C temperature coefficient when designing circuits sensitive to resistance variations over temperature ranges.
Part Context
This component belongs to the MAX5160/MAX5161 family of low-power digital potentiometers. The MAX5160 variant utilizes an 8-pin µMAX package and supports three-wire serial control. The 'L' designation specifically identifies the 50kΩ resistance option within this product line.
Replacement Considerations
Direct replacements include other MAX5160 variants with different resistance values or packages, such as MAX5160MEUA+ (100kΩ) or MAX5160NEUA+ (200kΩ). Ensure the replacement maintains the same pinout and package dimensions for board compatibility.
FAQ
What is the default wiper position at power-up?
The power-on reset circuitry sets the wiper position to midscale, which corresponds to position 16.
How many tap points are available on the MAX5160?
The device consists of a fixed resistor with 32 accessible tap points along the resistor string between the H and L terminals.
What is the ratiometric temperature coefficient of the resistor?
The MAX5160 has a ratiometric resistor temperature coefficient of 5ppm/°C, making it suitable for stable adjustable gain configurations.
