MAX542BCPD+

Digital To Analog Converters Overview

The MAX542BCPD+ 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 ±1 LSB integral nonlinearity (INL) and differential nonlinearity (DNL). The device features an unbuffered voltage output with a typical settling time of 1µs to ±1/2 LSB. It utilizes a 10MHz, 3-wire serial interface compatible with SPI/QSPI/MICROWIRE standards. The component includes a power-on reset circuit that clears the DAC output to 0V in unipolar mode upon initial power application.

Digital To Analog Converters Feature Summary

• Full 16-bit resolution without adjustments
• +5V single-supply operation
• Unbuffered voltage output directly drives loads greater than 60kΩ
• Schmitt trigger inputs for direct optocoupler interface

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CPD+' against the manufacturer's current ordering guide to confirm package type and RoHS compliance status. Ensure the commercial temperature range (0°C to +70°C) aligns with system requirements. Cross-reference the datasheet revision date to confirm pinout and electrical characteristics have not changed.

Digital To Analog Converters Selection Notes

Select this component when 16-bit accuracy is required with minimal external adjustments. The unbuffered output architecture reduces power consumption but requires load impedance above 60kΩ to maintain linearity. Use matched scaling resistors and an external precision op amp if bipolar output swing is necessary. Verify compatibility with the host microcontroller's serial clock speed and logic levels.

Digital To Analog Converters Part Context

This part belongs to the MAX541/MAX542 family of high-precision DACs. The MAX542 variant specifically includes internal matched scaling resistors and Kelvin-sense connections for reference and analog ground pins, facilitating bipolar operation with external amplifiers. It differs from the MAX541 by offering additional pins for these bipolar configuration features within a 14-pin plastic DIP package.
