MAX5444AEUB+

Digital To Analog Converters Overview

The MAX5444AEUB+ is a serial-input, voltage-output, 16-bit digital-to-analog converter (DAC) manufactured by Analog Devices / Maxim Integrated. It operates from a single +3V supply and features a 10-pin µMAX package. The device provides full 16-bit performance with ±2 LSB integral nonlinearity (INL) and ±1 LSB differential nonlinearity (DNL). Key electrical parameters include a 1µs output settling time, 120µA typical supply current, and a 25MHz serial interface compatible with SPI/QSPI/MICROWIRE standards. It includes an asynchronous clear function and power-on reset circuitry.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'AEUB+' to confirm the -40°C to +85°C temperature range and lead-free/RoHS compliance status. Ensure the ordering documentation matches the 10-pin µMAX package type required for this variant. Cross-reference the manufacturer's official datasheet for any recent revisions or pinout changes before finalizing procurement specifications.

Digital To Analog Converters Selection Notes

Select the MAX5444AEUB+ when bipolar operation with external op amps is required, as it contains matched scaling resistors. Verify that the system requires a +3V single supply rather than +5V. Confirm that the 16-bit resolution and unbuffered voltage output meet the load requirements, specifically ensuring load resistance exceeds 60kΩ to maintain linearity without degradation.

Digital To Analog Converters Part Context

This component belongs to the MAX5441–MAX5444 family of 16-bit DACs. The MAX5444 variant specifically supports +3V operation and utilizes a 10-pin package to accommodate bipolar mode internal resistors. It shares architectural similarities with the MAX5441–MAX5443 but differs in supply voltage compatibility and pin count compared to the 8-pin variants.

Digital To Analog Converters Replacement Considerations

Public confirmed substitute part numbers: MAX5444ACUB+, MAX5444BCUB+, MAX5444BEUB+. These variants share the same package and core functionality but differ in temperature range or linearity specifications.
