MAX5110GWX+T

Digital To Analog Converters Overview

The MAX5110GWX+T is a single-channel, nonvolatile digital potentiometer manufactured by Analog Devices Inc./Maxim Integrated. It features an I2C-compatible serial interface for setting the wiper position and storing data in EEPROM. The device offers 64 tap positions with a resistance tolerance of ±8% and operates within a supply voltage range of 2.7V to 5.5V. Packaged in a 8-pin SOIC (W) surface-mount package, it supports end-to-end resistances of 10kΩ, 50kΩ, or 100kΩ. Key specifications include a temperature coefficient of 35ppm/°C and low power consumption, making it suitable for precision analog control applications requiring persistent settings.

Digital To Analog Converters Feature Summary

• Nonvolatile memory retains wiper position after power loss
• I2C-compatible serial interface for simple control
• 64-tap resolution with ±8% resistance tolerance
• Wide supply voltage range: 2.7V to 5.5V

Digital To Analog Converters Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Digital volume control in audio systems
• Sensor biasing and calibration

Digital To Analog Converters Procurement Notes

Verify the specific end-to-end resistance value (10kΩ, 50kΩ, or 100kΩ) as the base part number MAX5110 may require suffixes to denote resistance options. Confirm the package type matches the design footprint, as variations exist between SOIC and TSSOP packages within the MAX5110 family. Check RoHS compliance status if required by local regulations.

Digital To Analog Converters Selection Notes

Select this component when nonvolatile storage of the wiper position is critical without external battery backup. Ensure the system voltage falls within the 2.7V to 5.5V operating range. Compare the 64-tap resolution against application requirements; higher resolution devices like the MAX5111 (128 taps) may be needed for finer control. Verify I2C bus compatibility and pull-up resistor requirements on the SDA and SCL lines.

Digital To Analog Converters Part Context

The MAX5110 belongs to the Maxim Integrated digital potentiometer family, designed to replace mechanical potentiometers in space-constrained PCB layouts. It integrates EEPROM for nonvolatile storage, eliminating the need for external memory chips. The GWX suffix indicates an 8-lead SOIC Wide package with industrial temperature range capabilities, distinguishing it from other package variants like the TSSOP.

Digital To Analog Converters Replacement Considerations

Direct replacements include the MAX5111 (128 taps, same interface) or MAX5112 (dual channel). Cross-vendor alternatives such as the AD5110 series offer similar functionality but may differ in pinout or electrical characteristics. Always verify register compatibility and physical dimensions before substitution.
