MAX5443ACUA+T

Digital To Analog Converters Overview

The MAX5443ACUA+T is a serial-input, voltage-output, 16-bit digital-to-analog converter (DAC) housed in an 8-pin µMAX package. It operates from a single +3V supply with a range of 2.7V to 3.6V and draws 120µA typical supply current. The device provides full 16-bit performance without adjustments, featuring ±2LSB integral nonlinearity (INL) and ±1LSB differential nonlinearity (DNL). It utilizes a 25MHz, 3-wire serial interface compatible with SPI/QSPI/MICROWIRE standards. The unbuffered output settles within 1µs for a full-scale step and directly drives loads greater than 60kΩ.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'CU' indicates the commercial temperature range of 0°C to +70°C. Confirm the '+T' designation corresponds to tape-and-reel packaging as specified in the manufacturer's documentation. Ensure compatibility with the required +3V single-supply voltage and verify that the external reference voltage meets the low-impedance requirements for maintaining 16-bit accuracy.

Digital To Analog Converters Selection Notes

Select this component when a compact 16-bit DAC is required for single-supply applications. The unbuffered output architecture minimizes power consumption and offset error, making it suitable for medium-load scenarios where RL exceeds 60kΩ. Consider the commercial temperature range if extended industrial temperatures are not necessary. Verify that the system can accommodate the asynchronous clear function and the specific power-on reset state of code 0.

Digital To Analog Converters Part Context

The MAX5443ACUA+T belongs to the MAX5441–MAX5444 family of serial-input, voltage-output, 16-bit DACs. This series offers full 16-bit performance with less than 2LSB INL and less than 1LSB DNL over temperature. The family includes variants operating from +5V supplies (MAX5441/MAX5442) and +3V supplies (MAX5443/MAX5444), available in both 8-pin and 10-pin µMAX packages depending on the specific model number.

Digital To Analog Converters Replacement Considerations

The MAX5443AEUA+T serves as a direct replacement offering the same electrical specifications but with an extended temperature range of -40°C to +85°C instead of the commercial 0°C to +70°C range.
