MAX5527GUA

Overview

The MAX5527GUA+ is a single-channel, linear-taper digital potentiometer IC manufactured by Analog Devices Inc./Maxim Integrated. It features 64 taps and utilizes a non-volatile memory architecture for wiper position storage. The device operates on a serial 2-wire interface and supports a supply voltage range of 2.7 V to 5.5 V, with a typical operating voltage of 5 V. Key electrical parameters include a resistance value of 100 kOhms, a tolerance of 25%, and a temperature coefficient of 35 PPM/°C. It functions within an extended industrial temperature range from -40°C to +105°C and consumes a low quiescent current of 1.5 µA.

Feature Summary

• Non-volatile memory retains wiper settings without power
• Single channel with 64 linear taps
• Serial 2-wire digital interface
• Low power consumption (1.5 µA)

Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Sensor calibration circuits

Procurement Notes

Verify component status as the product lifecycle indicates it may be obsolete or subject to discontinuation. Confirm RoHS compliance details through official documentation before procurement planning.

Selection Notes

Select this component for applications requiring precise, non-volatile resistance adjustment in space-constrained designs. Ensure the 100 kOhm resistance and 25% tolerance align with circuit requirements. Verify compatibility with the 2-wire serial protocol.

Part Context

This part belongs to the MAX5527 series of one-time programmable digital potentiometers. It shares architectural similarities with the MAX5528 but differs in specific configuration options. The GUA+ suffix denotes the UMAX-8 package and lead-free construction.

Replacement Considerations

Direct replacement candidates within the same family include the MAX5527GUA+ itself if available. Cross-model comparisons should consider the MAX5528GUA+ for similar functionality with potential pin-out or feature variations.
