MAX5443BEUA

Digital To Analog Converters Overview

The MAX5443BEUA+ 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. The device provides full 16-bit performance without adjustments, featuring ±4 LSB integral nonlinearity (INL) and ±1 LSB differential nonlinearity (DNL). It delivers unbuffered voltage outputs with a low supply current of 120µA typical. A 25MHz, 3-wire serial interface compatible with SPI/QSPI/MICROWIRE loads data into the DAC latch. The power-on reset circuit clears the output to code 0 upon initial power application.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm temperature range and package type. Ensure the selected variant matches the required operating conditions and electrical specifications for the target application design.

Digital To Analog Converters Selection Notes

Select this component when a 16-bit resolution and low power consumption are critical within a small footprint. Consider the unbuffered output impedance limitations if driving heavy loads, or utilize an external op-amp for bipolar operation requirements as detailed in the functional diagrams.

Digital To Analog Converters Part Context

This part belongs to the MAX5441–MAX5444 family of 16-bit DACs. The MAX5443 variant specifically supports +3V single-supply operation, distinguishing it from the MAX5441 which requires +5V. All variants share the same R-2R architecture and serial interface capabilities.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include MAX5441BEUA+ for +5V applications. Other series members like MAX5443AEUA+ offer extended temperature ranges.
