MAX5821LEUA

Digital To Analog Converters Overview

The MAX5821LEUA is a dual-channel, 10-bit digital-to-analog converter manufactured by Analog Devices Inc. under the Maxim Integrated brand. 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 and achieves a settling time of 4 µs. It supports differential nonlinearity (DNL) of ±0.5 LSB and integral nonlinearity (INL) of ±0.5 LSB. Operating within a temperature range of -40°C to +85°C, it is housed in an 8-lead uMAX package.

Digital To Analog Converters Feature Summary

• Dual-channel configuration providing independent 10-bit resolution per channel
• Low-power operation suitable for battery-powered applications
• Integrated buffered voltage output amplifiers
• Standard 2-wire I2C serial interface compatibility

Digital To Analog Converters Applications

• Portable instrumentation systems requiring low power consumption
• Battery-operated measurement devices
• Process control loops with limited channel density requirements
• Data acquisition systems utilizing I2C communication

Digital To Analog Converters Procurement Notes

Verify the specific suffix LEUA corresponds to the 8-lead uMAX package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations prior to integration. Ensure the component meets the required operating temperature range specifications for the intended environment.

Digital To Analog Converters Selection Notes

Select this component when dual-channel conversion is necessary within a compact footprint. Compare against the MAX5822 if higher 12-bit resolution is required, noting the trade-off in settling time. Verify that the external reference voltage requirements align with the system's available supply rails and accuracy constraints.

Digital To Analog Converters Part Context

This part belongs to the MAX5821 series of low-power DACs. It shares architectural similarities with the MAX5820 but offers increased resolution. The device complements the MAX5812 family, which provides single-channel options with varying bit depths. It is designed for applications prioritizing space efficiency and power management over high-speed throughput.

Digital To Analog Converters Replacement Considerations

The MAX5822LEUA serves as a higher-resolution alternative within the same package family. Designers requiring single-channel solutions may consider the MAX5812 series. Cross-reference pinouts and register maps carefully when substituting between different bit-depth variants in the same series.
