MAX5523EUA+T

Digital To Analog Converters Overview

The MAX5523EUA+T is a dual, 10-bit, ultra-low-power, voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply voltage ranging from 1.8V to 5.5V and consumes less than 5µA of supply current in normal operation. The device features rail-to-rail buffered voltage outputs and includes a precision internal reference that provides a buffered external reference output with unity-gain DAC outputs. A software-programmable shutdown mode reduces the overall current consumption, including the reference input current, to just 0.18µA. The unit utilizes a 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols.

Digital To Analog Converters Feature Summary

• Ultra-low power consumption with a dedicated shutdown mode reducing current to 0.18µA
• Integrated precision internal reference capable of sourcing up to 8mA for system use
• Glitch-free power-up sequence drives outputs to zero scale upon initialization
• Flexible 3-wire serial interface supporting standard communication protocols

Digital To Analog Converters Applications

• Portable battery-powered devices requiring extended operational life
• Instrumentation systems needing precise analog signal generation
• Automatic trimming and calibration circuits in factory or field environments
• Programmable voltage and current sources for industrial control
• Chemical sensor cell biasing for gas monitoring applications

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm package integrity and pin alignment against the 8-pin µMAX specification. Ensure environmental compliance documentation matches project requirements. Validate datasheet revision compatibility before integration into final designs.

Digital To Analog Converters Selection Notes

Select this model when an integrated internal reference is required to minimize board space. Choose over external reference variants if system design benefits from a unified power domain. Verify that the 10-bit resolution meets application accuracy needs. Confirm that the 3-wire interface aligns with available microcontroller resources.

Digital To Analog Converters Part Context

This component belongs to the MAX5522–MAX5525 family of dual, ultra-low-power, 10-bit voltage-output DACs. The MAX5523 variant specifically distinguishes itself by incorporating a precision internal reference and providing a buffered external reference output. Other family members offer external reference inputs or force-sense configurations depending on specific gain requirements.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same series include the MAX5522EUA, which accepts an external reference instead of using an internal one. For higher resolution requirements, the MAX5532–MAX5535 series offers 12-bit compatibility. Lower resolution alternatives are available in the MAX5512–MAX5515 series.
