MAX5442BCUB+T

Digital To Analog Converters Overview

The MAX5442BCUB+T is a serial-input, voltage-output, 16-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and provides full 16-bit performance with ±2LSB integral nonlinearity (INL) and ±1LSB differential nonlinearity (DNL). The device features an unbuffered voltage output capable of driving loads greater than 60kΩ, resulting in a low supply current of 120µA. It utilizes a 25MHz, 3-wire serial interface compatible with SPI/QSPI/MICROWIRE standards. The component is housed in a 10-pin µMAX package and includes matched scaling resistors for bipolar operation with an external op amp.

Digital To Analog Converters Feature Summary

• Ultra-small 10-pin µMAX package design
• Fast 1µs settling time for high-speed applications
• Unbuffered voltage output directly drives medium loads
• Power-on reset circuit clears DAC output to code 32768

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'T' against official documentation to confirm tape-and-reel packaging status, as standard listings may indicate tube packaging. Confirm the temperature range corresponds to the 'C' suffix for commercial operation. Ensure compatibility with the required +5V single-supply voltage and check for RoHS compliance markings on the final delivered components.

Digital To Analog Converters Selection Notes

Select this component when a 16-bit resolution is required with a +5V supply voltage. The MAX5442 supports bipolar output swings when used with an external precision op amp, unlike the MAX5441 which is unipolar only. Consider the 10-pin µMAX package size constraints and the need for an external reference voltage between 2V and VDD. Verify that the unbuffered output impedance is suitable for the intended load requirements.

Digital To Analog Converters Part Context

The MAX5442 belongs to the MAX5441–MAX5444 family of 16-bit serial-input DACs. This series offers compact solutions with R-2R architecture for low glitch energy. The MAX5442 specifically differs from the MAX5441 by providing internal matched scaling resistors for bipolar operation and powering up to mid-scale code 32768. It shares the same 25MHz serial interface and low power characteristics as its counterparts.

Digital To Analog Converters Replacement Considerations

Public confirmed substitute part numbers: MAX5442ACUB+, MAX5442AEUB+, MAX5442BEUB+. These variants share the same functional specifications but differ in temperature ranges and linearity grades.
