MAX542BCSD

Digital To Analog Converters Overview

The MAX542BCSD 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 ±2 LSB integral nonlinearity (INL) and differential nonlinearity (DNL) over the commercial temperature range of 0°C to +70°C. The device features an unbuffered output with low supply current of 0.3mA and includes Kelvin-sense connections for reference and analog ground pins. It utilizes a 10MHz, 3-wire serial interface compatible with SPI/QSPI/MICROWIRE standards.

Digital To Analog Converters Feature Summary

• Full 16-bit resolution without adjustments

• Industrial process control
• Automated test equipment
• Data-acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'SD' indicates the 14-pin SO package variant when sourcing replacements or verifying pinouts. Confirm the 'B' grade accuracy specifications match system requirements against other available grades like 'A' or 'C'. Ensure compatibility with existing PCB footprints for the SO-14 package type during component substitution processes.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high precision in a compact surface-mount form factor. Consider the unbuffered output impedance limitations when driving heavy loads. Evaluate the need for external op-amps if bipolar output swings are required, as the MAX542 supports this configuration with matched scaling resistors.

Digital To Analog Converters Part Context

This part belongs to the MAX541/MAX542 family of 16-bit DACs. The MAX542 variant specifically includes internal matched scaling resistors for bipolar operation with external amplifiers, distinguishing it from the MAX541. The 'BCSD' designation identifies the B-grade accuracy, commercial temperature range, and SOIC-14 packaging.

Digital To Analog Converters FAQ

How does the MAX542 support bipolar operation?

The MAX542 includes matched scaling resistors that connect to an external precision op amp, generating a ±VREF output swing.

What is the function of the Kelvin-sense connections?

Kelvin-sense connections for the reference and analog ground pins reduce layout sensitivity and improve accuracy by minimizing voltage drops in the sense lines.

Can the digital inputs interface directly with optocouplers?

Yes, Schmitt trigger inputs allow direct interfacing with optocouplers for applications requiring isolation without additional external logic.
