MAX5529GTA+

Overview

The MAX5529GTA+ is a single-channel digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It features a resistance value of 10kΩ and provides 64 tap positions for precise adjustment. The device utilizes a serial 2-wire interface for control and incorporates non-volatile memory to retain the wiper setting during power-off conditions. It operates on a single power supply ranging from 2.7V to 5.5V. The component is housed in an 8-pin μMAX surface-mount package with dimensions of 3.1mm x 3.1mm x 0.95mm, suitable for space-constrained applications.

Feature Summary

• 64-tap resolution with linear and logarithmic taper options
• Non-volatile memory retains wiper position after power cycle
• Serial 2-wire interface minimizes pin count requirements
• Operates within a 2.7V to 5.5V single-supply range

Applications

• Audio volume control systems requiring adjustable attenuation
• Programmable gain amplifier circuits
• Voltage reference adjustment in sensor interfaces
• LCD bias voltage tuning

Procurement Notes

Verify the specific suffix 'GTA+' against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with the required 2-wire serial protocol and check for lead-free compliance markings consistent with the '+' designation.

Selection Notes

Select this component when a single digital potentiometer with non-volatile storage is required. Confirm that the 10kΩ resistance value matches the circuit impedance needs. Verify that the 64-step resolution is sufficient for the application's precision requirements compared to higher-resolution alternatives.

Part Context

This part belongs to the MAX5528/MAX5529 family of one-time programmable digital potentiometers. These devices are designed to replace mechanical potentiometers in various analog signal conditioning applications, offering improved reliability and smaller form factors.

Replacement Considerations

Check for direct replacements within the MAX5528/MAX5529 series. Verify pinout compatibility and electrical specifications such as resistance tolerance and operating voltage range before substituting.
