MAX5529GTA

Overview

The MAX5529GTA is a digital potentiometer IC manufactured by Analog Devices Inc./Maxim Integrated. It features a single potentiometer circuit with 64 taps and a resistance value of 10kΩ. The device utilizes a serial 2-wire interface for control and includes non-volatile memory to retain settings. It operates on a single power supply ranging from 2.7V to 5.5V. The component is housed in an 8-pin μMAX package with surface mount installation, measuring 3.1mm x 3.1mm x 0.95mm. It supports linear and logarithmic taper configurations and functions within a temperature range of -40°C to +105°C.

Feature Summary

• 64-tap resolution with 10kΩ resistance
• Non-volatile memory storage
• Serial 2-wire interface
• Single supply voltage operation (2.7V to 5.5V)

Applications

• Audio volume control
• Sensor calibration
• Programmable gain amplifiers

Procurement Notes

Verify the specific suffix 'GTA' against official Maxim Integrated documentation to confirm package type and tape/reel specifications. Ensure compatibility with the required operating voltage range and interface protocols before integration into the design.

Selection Notes

Select this component when a compact, non-volatile digital potentiometer is required for applications needing precise resistance adjustment via a simple serial interface. Consider the 10kΩ resistance value and 64-step resolution against system requirements for linearity and power consumption.

Part Context

This part belongs to the MAX5528/MAX5529 family of one-time programmable, linear-taper digital potentiometers. These devices are designed for applications requiring adjustable resistance with persistent state retention without external backup power.

Replacement Considerations

Check for direct substitutes within the MAX5528 series or other Maxim digital potentiometers with similar pinouts and electrical characteristics. Verify that any replacement maintains the same interface protocol and memory type.
