MAX5442ACUB+

Digital To Analog Converters Overview

The MAX5442ACUB+ is a serial-input, voltage-output, 16-bit digital-to-analog converter (DAC) from the MAX544x family. It operates from a single +5V supply and features a 3-wire serial interface compatible with SPI/QSPI/MICROWIRE standards. The device provides full 16-bit performance with ±2 LSB integral nonlinearity (INL) and ±1 LSB differential nonlinearity (DNL). It includes an asynchronous clear input and a power-on reset circuit that initializes the output to code 32768. The DAC utilizes an inverted R-2R architecture for low glitch energy and supports unipolar or bipolar operation via external op amps.

Digital To Analog Converters Procurement Notes

Verify the component matches the exact part number MAX5442ACUB+. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated. Check the package type is 10-pin µMAX. Ensure the temperature range is 0°C to +70°C. Verify RoHS compliance status if required by your design specifications.

Digital To Analog Converters Selection Notes

Select this component when a 16-bit resolution is required with a single +5V supply. It is suitable for applications needing fast settling times and low power consumption. Consider the bipolar configuration capability if negative output voltages are needed using an external op amp. Ensure the serial interface timing meets the system's clock requirements.

Digital To Analog Converters Part Context

The MAX5442ACUB+ belongs to the MAX5441–MAX5444 series of 16-bit serial-input DACs. These devices share similar architectures but differ in supply voltage requirements and pin configurations. The MAX5442 specifically supports +5V operation and offers bipolar output capabilities through internal matched scaling resistors, distinguishing it from the unipolar-only MAX5441.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same series include MAX5442AEUB+, MAX5442BCUB+, and MAX5442BEUB+. These variants offer different temperature ranges and linearity specifications. Ensure the substitute maintains the 10-pin µMAX package and +5V supply requirement for pin-compatible integration.
