MAX5533EUA

Digital To Analog Converters Overview

The MAX5533EUA is a dual, 12-bit, ultra-low-power voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates on a single supply ranging from 1.8V to 5.5V and features rail-to-rail buffered outputs with an internal precision reference. The device consumes less than 5µA in normal operation and reduces current to 0.18µA in shutdown mode. It utilizes a 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE protocols. Packaged in an 8-pin µMAX format, it supports extended industrial temperatures from -40°C to +85°C.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements and interface standards before integration. Cross-reference datasheet revisions for any updates to electrical characteristics or pin configurations.

Digital To Analog Converters Selection Notes

Select this component when dual-channel output is required alongside minimal power usage. The internal reference simplifies design by removing external components. Verify that the 12-bit resolution meets application accuracy needs and that the serial interface timing aligns with the host controller capabilities.

Digital To Analog Converters Part Context

This part belongs to the MAX5532–MAX5535 family of dual DACs. While sharing core specifications, variants differ in reference configuration and output buffer topology. The MAX5533 specifically integrates an internal reference with unity-gain buffers, distinguishing it from models requiring external references or force-sense configurations.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same series include the MAX5532EUA, which uses an external reference but shares the same package and interface.
