MAX551AEUB+

Digital To Analog Converters Overview

The MAX551AEUB+ is a 12-bit, current-output, multiplying digital-to-analog converter (DAC) from Analog Devices Inc./Maxim Integrated. It operates on a single +4.5V to +5.25V supply and features an internal R-2R resistor array with NMOS current switches. The device utilizes a 3-wire serial interface compatible with SPI/QSPI and MICROWIRE standards, supporting clock frequencies up to 12.5MHz. Key electrical parameters include a typical settling time of 0.8µs, integral nonlinearity (INL) of ±0.5 LSB, and differential nonlinearity (DNL) of ±0.5 LSB. It offers low power consumption with a supply current of 0.4µA in standby mode. The component is housed in a space-saving 10-pin µMAX package.

Digital To Analog Converters Feature Summary

• Supports unipolar or bipolar output configurations using a single power supply.
• Includes an asynchronous clear input for resetting the DAC output to zero.
• Features double-buffered interface logic with separate input and DAC registers.

Digital To Analog Converters Applications

• Automatic Calibration
• Gain Adjustment
• Transducer Drivers
• Process-Control I/O Boards

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'E' confirms the extended temperature range of -40°C to +85°C. Confirm the 'UB+' suffix indicates the 10-pin µMAX package and RoHS compliance. Cross-reference the manufacturer's latest datasheet revision to ensure pinout compatibility and updated electrical specifications before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution and multiplying capability are required within a compact footprint. Ensure the system design accommodates the 10-pin µMAX package dimensions. Verify that the application requires a current-output architecture or includes necessary external amplification circuitry for voltage conversion.

Digital To Analog Converters Part Context

This part belongs to the MAX551/MAX552 family of serial multiplying DACs. The MAX551 variant is designed for +5V operation, while the MAX552 supports +3V supplies. The MAX551AEUB+ specifically denotes the industrial temperature grade and surface-mount packaging within this series.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same package and specification include the MAX551ACUB+ and MAX551BCUB+. These alternatives share identical pinouts and functionality but differ in linearity accuracy grades and operating temperature ranges.
