MAX5160MEUA+

Overview

The MAX5160MEUA+ is a low-power digital potentiometer featuring 32 tap positions and a nominal resistance of 100kΩ. It operates on a single supply voltage ranging from +2.7V to +5.5V with a typical supply current of 10µA. The device utilizes a 3-wire serial interface (CS, U/D, INC) for wiper control and includes power-on reset functionality that sets the wiper to midscale. Packaged in an 8-pin µMAX format, it supports an extended industrial temperature range of -40°C to +85°C.

Feature Summary

• 32 Tap Positions with Linear Taper
• 100kΩ Nominal Resistance Value
• 3-Wire Serial Data Input Interface
• ±25% Resistance Tolerance

Applications

• LCD Screen Adjustment
• Volume Control
• Mechanical Potentiometer Replacement

Procurement Notes

Verify the component against official Maxim Integrated datasheets to confirm the specific 100kΩ resistance value associated with the MEUA suffix. Ensure compatibility with the required 3-wire serial protocol and check for availability constraints as distribution status may vary by region.

Selection Notes

Select this component when a digitally controlled variable resistor with 32 discrete steps is required. The 100kΩ value suits moderate impedance applications. Verify that the system can accommodate the 8-pin µMAX package dimensions and that the operating voltage remains within the 2.7V to 5.5V range.

Part Context

This part belongs to the MAX5160/MAX5161 family of low-power digital potentiometers. The MAX5160 variant specifically offers an 8-pin configuration with separate high and low terminals, distinguishing it from the 6-pin MAX5161 which functions as a variable resistor.

Replacement Considerations

Direct substitutes include other MAX5160 variants with different resistance values, such as MAX5160LEUA+ (50kΩ) or MAX5160NEUA+ (200kΩ), provided the circuit impedance requirements are adjusted accordingly.
