MAX5443AEUA+T

Digital To Analog Converters Overview

The MAX5443AEUA+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. The device provides full 16-bit performance without adjustments, featuring ±2LSB Integral Nonlinearity (INL) and ±0.5LSB Differential Nonlinearity (DNL). It utilizes a 25MHz, 3-wire serial interface compatible with SPI/QSPI/MICROWIRE standards. The unbuffered output draws a typical supply current of 120µA and settles within 1µs for a full-scale step. The operating temperature range extends from -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Ultra-small 8-pin µMAX package measuring 3mm x 5mm
• Low power consumption with 120µA supply current
• Fast 1µs settling time for full-scale transitions
• Unbuffered voltage output capable of driving loads greater than 60kΩ

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'EUA' corresponds to the extended temperature range (-40°C to +85°C) and the 8-pin µMAX package configuration. Confirm RoHS compliance status indicated by the '+' symbol. Ensure the design supports single-supply operation at +3V. Check for availability constraints as this component may be subject to limited supply conditions or factory special orders.

Digital To Analog Converters Selection Notes

Select the MAX5443AEUA+T when bipolar operation is not required, as it defaults to unipolar code 0 upon power-on reset. For bipolar applications requiring mid-scale initialization, consider the MAX5444 variant instead. Ensure the external reference voltage source has low impedance to maintain 16-bit accuracy. Verify that the load resistance exceeds 60kΩ to prevent degradation of linearity specifications in unbuffered mode.

Digital To Analog Converters Part Context

This component belongs to the MAX5441–MAX5444 family of 16-bit DACs manufactured by Analog Devices / Maxim Integrated. The family shares identical architecture but differs in supply voltage requirements (+3V vs +5V), pin count (8-pin vs 10-pin), and power-on reset states. The MAX5443 specifically targets low-voltage +3V systems with an 8-pin footprint.

Digital To Analog Converters Replacement Considerations

The MAX5443ACUA+ serves as a commercial grade alternative with a 0°C to +70°C temperature range. The MAX5444AEUB+ offers similar electrical characteristics but includes matched scaling resistors for bipolar operation in a 10-pin package.
