MAX5160NEUA+T

Overview

The MAX5160NEUA+T is a low-power digital potentiometer IC manufactured by Analog Devices (Maxim Integrated). It provides digitally controlled resistance with 32 tap positions and a nominal end-to-end resistance of 200kΩ. The device operates on a single supply voltage ranging from +2.7V to +5.5V, drawing a typical supply current of 10µA. It features a linear taper, ±25% resistance tolerance, and a wiper resistance of 400Ω. The component utilizes a 3-wire serial interface for control and includes power-on reset functionality that sets the wiper to midscale upon initialization.

Feature Summary

• 32 Tap Positions: Provides precise digital adjustment across the resistor string.
• Low Power Consumption: Typical supply current of 10µA at +5V operation.
• Linear Taper: Offers a nominal temperature coefficient of 50ppm/°C end-to-end.
• Power-On Reset: Automatically initializes the wiper position to midscale (position 16).

Applications

• LCD Screen Adjustment
• Volume Control
• Mechanical Potentiometer Replacement

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure compatibility with the required resistance value, as the MAX5160 series offers multiple options including 50kΩ and 100kΩ variants alongside the 200kΩ version specified in this model number.

Selection Notes

Select the MAX5160NEUA+T when a 200kΩ digital potentiometer is required in an 8-pin µMAX package. Confirm that the application supports the 3-wire serial interface and that the operating voltage falls within the 2.7V to 5.5V range. Consider the ±25% tolerance and 400Ω wiper resistance for circuit accuracy requirements.

Part Context

This component belongs to the MAX5160/MAX5161 family of low-power digital potentiometers. The MAX5160 variant specifically uses an 8-pin µMAX package and requires three control lines (CS, INC, U/D), distinguishing it from the 6-pin SOT23 packaged MAX5161 which has internal connections for simplified wiring.

Replacement Considerations

Direct substitutes include other MAX5160 variants with different resistance values or packages, such as MAX5160MEUA+ (100kΩ) or MAX5160LEUA+ (50kΩ). Verify pinout compatibility and electrical specifications before substituting.
