MAX5160NEUA+

Overview

The MAX5160NEUA+ is a low-power, linear-taper digital potentiometer manufactured by Analog Devices (Maxim Integrated). It functions as a digitally controlled variable resistor 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 and draws a typical supply current of 10µA. It features a 3-wire serial interface for wiper control, ±25% resistance tolerance, and a nominal temperature coefficient of 50ppm/°C. Packaged in an 8-pin µMAX format, it includes power-on reset functionality that sets the wiper to midscale upon initialization.

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 across the full voltage range.
• Serial Interface Control: Utilizes a 3-wire serial input (CS, INC, U/D) for wiper position updates.
• Power-On Reset: Automatically initializes the wiper to midscale (position 16) at startup.

Applications

• LCD Screen Adjustment
• Volume Control
• Mechanical Potentiometer Replacement

Procurement Notes

Verify the specific ordering suffix 'NEUA+' against official manufacturer documentation to confirm the 200kΩ resistance value and package type. Ensure compatibility with the required operating temperature range of -40°C to +85°C for industrial applications.

Selection Notes

Select this component when a 200kΩ linear taper digital potentiometer is required. Consider the 3-wire serial interface requirements and the 8-pin µMAX package constraints. Verify that the application can accommodate the ±25% resistance tolerance and the specific wiper settling time characteristics.

Part Context

This part belongs to the MAX5160/MAX5161 family of low-power digital potentiometers. The MAX5160 variant specifically utilizes an 8-pin µMAX package and supports three-terminal operation, distinguishing it from the 6-pin SOT23 packaged MAX5161 which integrates the wiper to the high terminal.

Replacement Considerations

Direct substitutes within the same series include MAX5160MEUA+ (100kΩ) and MAX5160LEUA+ (50kΩ), provided the resistance value matches the circuit design. Other pin-compatible options require verification of electrical parameters such as wiper resistance and supply voltage limits.
