MAX542AEPD

Digital To Analog Converters Overview

The MAX542AEPD is a serial-input, voltage-output, 16-bit digital-to-analog converter (DAC) operating from a single +5V supply. It provides full 16-bit performance with ±1LSB INL and DNL without adjustments. The unbuffered output ensures low power consumption of 0.3mA and a low offset error of 1LSB. The DAC output range spans 0V to VREF in unipolar mode, or ±VREF in bipolar mode using matched scaling resistors and an external op amp. A 10MHz, 3-wire serial interface compatible with SPI/QSPI/MICROWIRE loads data into the DAC latch. Power-on reset clears the output to 0V upon initial application.

Digital To Analog Converters Feature Summary

• Full 16-bit resolution guaranteed over temperature without external adjustments
• Unbuffered voltage output architecture for low power consumption
• Schmitt-trigger inputs enable direct optocoupler interface
• Kelvin-sense connections reduce layout sensitivity for reference and analog ground

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C compared to commercial variants. Confirm the 'PD' package designation corresponds to the 14-pin plastic DIP form factor. Ensure compatibility with the required serial interface protocol before integration.

Digital To Analog Converters Selection Notes

Select this component when 16-bit accuracy is required with minimal power dissipation. The unbuffered output is suitable for loads greater than 60kΩ. For bipolar operation, an external precision op amp must be included in the design. Verify that the system ground plane separation meets the low-impedance requirements for analog and digital grounds.

Digital To Analog Converters Part Context

This device belongs to the MAX541/MAX542 family of high-resolution DACs. The MAX542 variant specifically includes matched bipolar offset resistors and Kelvin connections not present in the MAX541. The 'A' grade specifies tighter linearity tolerances compared to 'B' or 'C' grades within the same package and temperature range.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other MAX542AEPD units or MAX542AESD for surface mount applications. Lower grade versions like MAX542BCPD offer wider linearity tolerances. The MAX541 series lacks bipolar scaling resistors and uses an 8-pin package.
