MAX5820MEUA+T

Digital To Analog Converters Overview

The MAX5820MEUA+T is a dual, 8-bit voltage-output digital-to-analog converter (DAC) featuring an I²C-compatible 2-wire serial interface. It operates from a single 2.7V to 5.5V supply with typical current consumption of 115µA at 3.6V and 135µA at 5.5V. The device includes internal precision rail-to-rail output buffers and settles to ±0.5 LSB within 4µs. Static accuracy specifications include integral nonlinearity (INL) of ±0.5 LSB and differential nonlinearity (DNL) of ±0.5 LSB. It supports three software-selectable power-down modes reducing current to less than 1µA. The component is specified over the -40°C to +85°C temperature range and is housed in an 8-pin µMAX package.

Digital To Analog Converters Feature Summary

• Ultra-low power operation with programmable power-down modes and Schmitt-trigger inputs for direct optocoupler interfacing
• Internal power-on reset circuit ensuring zero-scale initialization upon power-up

Digital To Analog Converters Applications

• Digital gain and offset adjustments
• Programmable voltage and current sources
• Battery-operated instrumentation
• VCO/Varactor diode control

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm pin configuration and address settings. Ensure compatibility with system voltage levels and I²C bus timing requirements before integration. Confirm RoHS compliance status through official certification documents provided by Analog Devices or Maxim Integrated.

Digital To Analog Converters Selection Notes

Select this component for designs requiring low-power, dual-channel DAC functionality with minimal external components. The integrated buffers eliminate the need for external amplifiers, while the small 8-pin µMAX package suits space-constrained layouts. Consider the MAX5821 or MAX5822 if higher resolution is required for the application.

Digital To Analog Converters Part Context

This part belongs to the MAX5820 series of low-power, 2-wire serial DACs manufactured by Analog Devices / Maxim Integrated. It shares architectural similarities with the MAX5821 (10-bit) and MAX5822 (12-bit) variants, offering a scalable solution for applications needing different resolution levels within the same package footprint and interface protocol.

Digital To Analog Converters Replacement Considerations

The MAX5821LEUA+ and MAX5822LEUA+ are documented vertical replacements offering 10-bit and 12-bit resolutions respectively, maintaining the same 8-pin µMAX package and I²C interface.
