MAX544AESA+

Digital To Analog Converters Overview

The MAX544AESA+ is a serial-input, voltage-output, 14-bit digital-to-analog converter (DAC) from Analog Devices/Maxim Integrated. It operates from a single +5V supply and provides full 14-bit performance with ±0.5LSB INL and ±0.9LSB DNL over temperature without adjustments. The device features an unbuffered voltage output that directly drives loads greater than 60kΩ, resulting in low power consumption of 1.5mW and a low offset error of 0.6mV. It utilizes a 10MHz, 3-wire serial interface compatible with SPI/QSPI/MICROWIRE standards. The component is housed in an 8-pin SO package and supports an operating temperature range of -40°C to +85°C.

Digital To Analog Converters Feature Summary

• Full 14-bit resolution maintained across the operating temperature range without requiring external calibration or adjustments.
• Unbuffered voltage output architecture minimizes power consumption and offset errors while supporting medium-load driving capabilities.
• Integrated power-on reset circuit ensures the DAC output initializes to 0V in unipolar mode upon system power-up.

Digital To Analog Converters Applications

• Digital offset and gain adjustment circuits
• Industrial process control systems
• Automated test equipment

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'A' indicates the extended temperature grade (-40°C to +85°C) compared to commercial variants. Confirm the 'E' denotes the SOIC narrow package type. Ensure compatibility with existing PCB footprints for the 8-pin SO configuration before procurement.

Digital To Analog Converters Selection Notes

Select this component when 14-bit accuracy is required with minimal power consumption. The unbuffered output is suitable for high-impedance loads exceeding 60kΩ. For bipolar operation or lower impedance requirements, consider the pin-compatible MAX545 which includes internal scaling resistors and Kelvin connections.

Digital To Analog Converters Part Context

This part belongs to the MAX544/MAX545 family of 14-bit DACs. It shares architectural similarities with the MAX541/MAX542 series but offers 14-bit precision instead of 16-bit. The MAX544 serves as the unipolar-only variant within the 8-pin package lineup, distinct from the MAX545 which supports bipolar configurations.

Digital To Analog Converters Replacement Considerations

The MAX544BCSA+ is a pin-compatible alternative offering commercial temperature range (0°C to +70°C) with ±1LSB INL. Verify if the extended temperature rating of the MAX544AESA+ is critical for the application before substituting.
