MAX5533EUA+T

Digital To Analog Converters Overview

The MAX5533EUA+T is a dual, 12-bit, ultra-low-power, voltage-output digital-to-analog converter (DAC) in an 8-pin μMAX package. It operates from a single supply ranging from 1.8V to 5.5V and consumes less than 5μA during normal operation. The device features a precision internal reference that provides a buffered external reference output with unity-gain DAC outputs. It utilizes a 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. Upon power-up, the outputs are driven to zero scale for glitch-free startup.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with rail-to-rail buffered voltage outputs
• Integrated precision internal reference with configurable output voltages
• Ultra-low power consumption with software-programmable shutdown mode
• Glitch-free power-up behavior driving outputs to zero scale

Digital To Analog Converters Applications

• Portable battery-powered devices
• Instrumentation systems
• Automatic trimming and calibration in factory or field environments
• Programmable voltage and current sources
• Industrial process control and remote industrial devices

Digital To Analog Converters Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the presence of the + suffix indicates lead-free compliance. Ensure the ordering suffix matches the required package type and temperature range before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this model when a dual-channel DAC with an integrated reference is required. Choose between MAX5532 and MAX5533 based on whether an external or internal reference source is preferred. Verify that the 12-bit resolution and 1.8V to 5.5V supply range meet system requirements.

Digital To Analog Converters Part Context

This component belongs to the MAX5532–MAX5535 family of dual, 12-bit, ultra-low-power DACs. The MAX5533 variant specifically integrates a precision internal reference, distinguishing it from the MAX5532 which requires an external reference. Both share identical pinouts and functionality within the 8-pin μMAX package.

Digital To Analog Converters Replacement Considerations

The MAX5532EUA+T serves as a direct functional substitute if an external reference is utilized. For higher resolution needs, consider the MAX5542/MAX5543 series. Ensure any replacement maintains the 8-pin μMAX footprint and compatible serial interface timing.
