Overview
The MAX5161NEZT+T is a low-power digital potentiometer featuring 32 tap positions and a 6-pin SOT-23 package. It operates on a single supply voltage ranging from +2.7V to +5.5V with a typical supply current of 100nA. The device provides three resistance values: 50kΩ, 100kΩ, and 200kΩ, with a nominal end-to-end temperature coefficient of 50ppm/°C and a ratiometric coefficient of 5ppm/°C. It includes power-on reset functionality that sets the wiper to midscale (position 16) upon initialization.
Feature Summary

Procurement Notes
Verify the specific resistance value associated with the NEZ suffix by consulting the manufacturer's selector guide or official datasheet ordering information. Confirm RoHS compliance status and ensure the component meets the required extended industrial temperature range specifications for the intended application environment.
Selection Notes
Select this component when a digitally controlled variable resistor is required in a compact 6-pin SOT-23 footprint. It is suitable for applications needing low quiescent current and precise linearity. Ensure the control interface supports the two-line serial input method used by the MAX5161 variant.
Part Context
This part belongs to the MAX5160/MAX5161 family of low-power digital potentiometers. While the MAX5160 utilizes an 8-pin µMAX package and requires three control lines, the MAX5161 uses a 6-pin SOT-23 package and internally connects the chip-select pin to ground, requiring only two control lines.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation.
FAQ
How does the MAX5161 differ from the MAX5160?
The MAX5161 uses a 6-pin SOT-23 package instead of the 8-pin µMAX package found in the MAX5160. Additionally, the MAX5161 internally connects the CS pin to ground and shorts the wiper terminal to the high terminal, acting as a variable resistor controlled by two lines.
What is the default wiper position at power-up?
The device features power-on reset circuitry that automatically sets the wiper position to midscale, which corresponds to position 16 out of 32 taps.
What is the maximum INC frequency for the MAX5161?
The maximum INC frequency is specified as 7MHz under standard operating conditions.
