MAX5528GTA

Overview

The MAX5528GTA+ is a single-channel, linear-taper digital potentiometer featuring 64 taps and non-volatile memory. It operates with a 5V supply and draws 1.5µA of current. The device utilizes a 2-wire serial interface for control. Key electrical parameters include a 50kΩ resistance value, ±25% tolerance, and a temperature coefficient of 35 PPM/°C. It functions within an industrial temperature range of -40°C to +105°C and is housed in an 8-lead UMAX package.

Feature Summary

• Non-volatile storage retains wiper position after power loss
• Single channel with 64 discrete tap positions
• Linear taper characteristic for precise resistance adjustment
• Low power consumption of 1.5µA at 5V operation

Applications

• Programmable gain amplifier circuits
• Voltage reference trimming
• Sensor bias adjustment
• Audio volume control systems

Procurement Notes

Verify component authenticity through authorized channels as the part may be subject to obsolescence notices. Confirm RoHS compliance status and check for specific manufacturer discontinuation notifications prior to procurement planning.

Selection Notes

Select this component when a single-channel, non-volatile digital potentiometer with 64 steps is required. Ensure the 50kΩ resistance value and 5V operating voltage align with system requirements. Verify that the 2-wire serial interface is compatible with the host controller.

Part Context

This component belongs to the MAX5528 family of one-time programmable digital potentiometers. It serves as a solid-state alternative to mechanical potentiometers in applications requiring adjustable resistance without moving parts.

Replacement Considerations

Check for direct pin-compatible replacements within the same series or verify functional equivalents from other manufacturers offering similar non-volatile digital potentiometer specifications.
