MAX5160MEUA

Overview

The MAX5160MEUA+ is a low-power, linear-taper 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, INC, U/D) for wiper control and includes power-on reset functionality that sets the wiper to midscale. Key electrical characteristics include ±25% resistance tolerance, 400Ω wiper resistance, and an end-to-end temperature coefficient of 50ppm/°C.

Feature Summary

• 32 Tap Positions: Provides precise digital adjustment between high and low terminals.
• Low Power Consumption: Operates with a typical supply current of 10µA at +5V.
• Glitchless Switching: Ensures stable operation during transitions between resistor taps.
• Power-On Reset: Automatically initializes the wiper position to midscale upon power-up.

Applications

• LCD Screen Adjustment
• Volume Control
• Mechanical Potentiometer Replacement

Procurement Notes

Verify the component marking 'MAX5160MEUA' against the datasheet selector guide to confirm the 100kΩ resistance value. Ensure the package matches the 8-pin µMAX specification. Check RoHS compliance status as indicated in the ordering information section.

Selection Notes

Select this part when a digitally controlled variable resistor with a 100kΩ nominal value is required. The 3-wire serial interface necessitates three control lines; consider the MAX5161 variant if only two lines are available or if a variable resistor configuration is preferred. Verify that the 32-step resolution meets the application's precision requirements.

Part Context

The MAX5160MEUA+ belongs to the MAX5160/MAX5161 family of low-power digital potentiometers. The suffix 'M' indicates the -40°C to +85°C extended industrial temperature range, while 'EUA' specifies the 8-pin µMAX package. This model serves as a direct electronic replacement for mechanical potentiometers in space-constrained designs.

Replacement Considerations

The MAX5160NEUA is a compatible alternative offering the same 8-pin µMAX package but with a 200kΩ resistance value. The MAX5160LEUA provides a 50kΩ option in the identical package. No other direct substitutes with identical pinouts and parameters are documented.
