MAX5443ACUA

Digital To Analog Converters Overview

The MAX5443ACUA+ 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 +3V supply and features an unbuffered output with a settling time of 1µs. The device utilizes a 25MHz, 3-wire serial interface compatible with SPI/QSPI/MICROWIRE standards. Key electrical specifications include ±2LSB integral nonlinearity (INL), ±0.5LSB differential nonlinearity (DNL), and a positive supply current of 120µA typical. It is housed in an 8-pin µMAX package and supports an operating temperature range of 0°C to +70°C.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'CUA' corresponds to the commercial temperature range (0°C to +70°C) and the 8-pin µMAX package configuration as defined in the official Maxim Integrated datasheet. Confirm RoHS compliance status indicated by the '+' suffix. Ensure the design accommodates the external reference requirements and power-on reset behavior specific to the MAX5443 variant.

Digital To Analog Converters Selection Notes

Select the MAX5443ACUA+ when a single +3V supply is required for 16-bit resolution applications. This part provides unipolar output capability with a power-on reset to code 0. Compare against the MAX5441 series if a +5V supply is preferred, or consider the MAX5444 series if bipolar output swing and a 10-pin package are necessary for the system architecture.

Digital To Analog Converters Part Context

The MAX5443ACUA+ belongs to the MAX5441–MAX5444 family of serial-input, voltage-output, 16-bit DACs. These devices are designed to offer full 16-bit performance over temperature without adjustments. The family shares a common architecture but varies in supply voltage (+3V vs +5V), pin count (8-pin vs 10-pin), and output polarity (unipolar vs bipolar).

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same package and specification include the MAX5443AEUA+ for extended temperature range (-40°C to +85°C). For higher precision, the MAX5443BCUA+ offers ±4LSB INL. Cross-family replacements like the MAX5441 require +5V supply adjustment.
