MAX550AEUA+

Digital To Analog Converters Overview

The MAX550AEUA+ is a single-channel, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices/Maxim Integrated. It operates on a single +2.5V to +5.5V supply with a typical operating current of 75µA at VDD = 2.5V. The device features an asynchronous load input and requires an external reference voltage. It utilizes a 10MHz, 3-wire serial interface compatible with SPI/QSPI and Microwire standards. The unit guarantees ±1LSB total unadjusted error over temperature and includes a shutdown mode reducing current drain to less than 1µA. It is housed in an 8-pin µMAX package.

Digital To Analog Converters Procurement Notes

Verify the component authenticity by checking the manufacturer markings against official documentation. Confirm the specific suffix indicates the extended industrial temperature range (-40°C to +85°C). Ensure the package type matches the required footprint for your design. Cross-reference the datasheet revision to confirm pinout consistency before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a single-channel DAC with low power consumption is required. It is suitable for applications needing an external reference source and asynchronous update capabilities. Consider the 8-bit resolution and unbuffered output impedance when designing the analog load circuitry. Verify that the system can accommodate the 3-wire serial interface timing requirements.

Digital To Analog Converters Part Context

This part belongs to the MAX548A/MAX549A/MAX550A family of low-power DACs. While the MAX548A uses VDD as the reference and the MAX549A lacks an asynchronous load input, the MAX550AEUA+ specifically combines single-channel operation with an external reference and asynchronous load functionality. All variants share similar power characteristics and serial interface protocols.

Digital To Analog Converters Replacement Considerations

Direct functional replacements within the same series include the MAX548AEUA+ and MAX549AEUA+. Note that the MAX548AEUA+ uses VDD as the reference, while the MAX549AEUA+ lacks the asynchronous LDAC input. Ensure any substitute matches the 8-pin µMAX package and the -40°C to +85°C temperature rating.
