MAX5468EUT+T

Overview

The MAX5468EUT+T is a linear-taper digital potentiometer configured as a variable resistor with a 10kΩ end-to-end resistance. It features 32 digitally controlled tap points managed via a 2-wire serial interface (CS and U/D). The device operates on a single +2.7V to +5.5V supply, drawing 0.3µA in standby mode. It includes power-on reset to midscale, glitchless switching between taps, and an integral nonlinearity of ±0.5 LSB. The component is housed in a 6-pin SOT23 package and functions over a -40°C to +85°C temperature range.

Feature Summary

• Configured as a variable resistor with 10kΩ nominal resistance
• 32-tap resolution with glitchless switching
• Ultra-low standby current of 0.3µA
• Power-on reset to midscale position

Applications

• LCD screen adjustment
• Volume control
• Mechanical potentiometer replacement
• Gain adjustment
• Line impedance matching

Procurement Notes

Verify the ordering suffix 'T' indicates tape-and-reel packaging configuration. Confirm the '+T' designation aligns with lead-free manufacturing standards specified by the manufacturer. Ensure the 6-pin SOT23 package code matches the required footprint for the target PCB design.

Selection Notes

Select this part when a variable resistor configuration is required rather than a potentiometer setup. The 10kΩ value suits applications needing lower resistance ranges compared to the 50kΩ or 100kΩ variants. Verify that the 2-wire serial interface timing requirements meet the system's clock speed constraints.

Part Context

This component belongs to the MAX5460–MAX5468 FleaPoT family of digital potentiometers. While other family members offer 50kΩ or 100kΩ values, the MAX5468 specifically provides the 10kΩ option. It shares the same interface and low-power characteristics but differs in internal resistor array scaling and wiper resistance specifications.

Replacement Considerations

Direct functional substitutes within the same family include MAX5467EUT+T (variable resistor, 10kΩ) if pin compatibility allows, though MAX5467 is typically 6-pin SC70. Cross-package replacements require verifying pinout alignment between SOT23 and SC70 footprints.
