MAX5821LEUA+T

Digital To Analog Converters Overview

The MAX5821LEUA+T is a dual-channel, 10-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It features a resistor-string architecture with buffered voltage outputs and operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. The device communicates via a 2-wire I2C serial interface. Key performance metrics include a settling time of 4 µs, differential nonlinearity (DNL) of ±0.5 LSB, and integral nonlinearity (INL) of ±0.5 LSB. It functions within an industrial temperature range of -40°C to +85°C and is housed in an 8-lead uMAX package.

Digital To Analog Converters Feature Summary

• Dual-channel configuration providing independent 10-bit resolution for two separate output channels.
• Integrated buffered voltage outputs eliminate the need for external amplifiers in many applications.
• Low-power operation designed for battery-powered or energy-efficient systems.
• Simple 2-wire serial interface compatible with standard I2C protocols.

Digital To Analog Converters Applications

• Portable instrumentation requiring low power consumption
• Battery-operated measurement devices
• Process control systems with limited channel count

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'LEUA' against official datasheets to confirm package type and temperature grade. Ensure compatibility with I2C bus speeds and voltage levels before integration. Check for RoHS compliance status as indicated in manufacturer documentation. Confirm availability through authorized distributors given potential lifecycle changes.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 10-bit resolution is sufficient and low power is critical. Compare DNL/INL specifications against system accuracy requirements. Consider the uMAX package size constraints relative to PCB layout. Evaluate if the 4 µs settling time meets dynamic signal requirements.

Digital To Analog Converters Part Context

This part belongs to the MAX582x series of low-power DACs. It shares architectural similarities with the MAX5822 but offers lower 10-bit resolution compared to the 12-bit variants. The series emphasizes compact packaging and minimal external component count for cost-sensitive designs.

Digital To Analog Converters Replacement Considerations

The MAX5822LEUA+T serves as a higher-resolution alternative within the same package family. Verify pinout compatibility before substitution. The MAX5812LEUT+T offers single-channel operation in a smaller SOT-23-6 package.
