MAX5143EUA+

Digital To Analog Converters Overview

The MAX5143EUA+ is a serial-input, voltage-output, 14-bit digital-to-analog converter in an 8-pin µMAX package. It operates from a single +3V supply with a typical supply current of 120µA. The device provides full 14-bit performance with ±1LSB INL and DNL over the -40°C to +85°C temperature range without adjustments. It features a 25MHz 3-wire serial interface compatible with SPI/QSPI/MICROWIRE standards. The unbuffered output settles within 1µs and directly drives loads greater than 60kΩ.

Digital To Analog Converters Feature Summary

• Miniature 8-pin µMAX package reduces footprint by 50% compared to standard SO packages
• Unbuffered voltage output architecture enables low power consumption and minimal offset error
• Integrated Schmitt-trigger inputs allow direct interfacing with optocouplers for isolation applications
• Power-on reset circuit ensures deterministic output state upon initial power application

Digital To Analog Converters Applications

• High-resolution gain adjustment circuits
• Industrial process control systems
• Automated test equipment
• Data-acquisition systems

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized Analog Devices or Maxim Integrated distributors. Confirm the specific suffix indicates the correct supply voltage variant (+3V) and package type (8-pin µMAX). Check for RoHS compliance status as manufacturing processes may evolve. Ensure the source document matches the official datasheet revision for accurate electrical specifications.

Digital To Analog Converters Selection Notes

Select this component when space-constrained designs require high-resolution analog output with low power consumption. The +3V supply operation makes it suitable for battery-powered or low-voltage logic systems. The unbuffered output is ideal for driving high-impedance loads or connecting to external amplifiers where additional offset errors must be avoided. Verify that the 14-bit accuracy meets system requirements without needing external trimming.

Digital To Analog Converters Part Context

This device belongs to the MAX5141–MAX5144 family of 14-bit DACs. The MAX5143 variant specifically supports +3V single-supply operation and utilizes an 8-pin µMAX package. Other family members include +5V variants (MAX5141/MAX5142) and bipolar output versions (MAX5142/MAX5144) housed in 10-pin packages. All share the same core architecture and serial interface compatibility.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitutes are not available in the provided documentation. Designers should verify pinout compatibility and electrical characteristics if considering alternative manufacturers. Note that ordering suffixes define supply voltage and package dimensions; ensure any replacement matches these physical and electrical constraints.
