MAX552AEUB

Digital To Analog Converters Overview

The MAX552AEUB is a 12-bit, current-output, multiplying digital-to-analog converter (DAC) from Analog Devices Inc./Maxim Integrated. It operates on a single +3V supply (+2.7V to +3.6V). The device features a 3-wire serial interface compatible with SPI/QSPI and MICROWIRE standards, supporting clock speeds up to 12.5MHz. It includes an internal power-on-reset circuit that clears all DAC registers upon power-up, setting the output to zero. The µMAX package provides an asynchronous clear input for immediate register clearing. Typical supply current is 0.4µA in shutdown mode.

Digital To Analog Converters Feature Summary

• Supports unipolar or bipolar output operation using a single power supply
• Features double-buffered interface logic with separate input and DAC registers
• Includes Schmitt-trigger digital inputs for direct optocoupler interface compatibility
• Provides an asynchronous clear input to reset DAC outputs to zero

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C. Confirm the 'U' suffix corresponds to the 10-pin µMAX package. Ensure the 'A' suffix matches the required linearity specification of ±1/2 LSB. Cross-reference the manufacturer's latest datasheet for any pinout or electrical characteristic updates before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution and multiplying capability are required within a low-power, single-supply environment. The MAX552 variant is specifically designed for +3V systems, distinguishing it from the MAX551 which supports +5V. Consider the 10-pin µMAX package size constraints and the necessity for the asynchronous clear feature when evaluating this part against other serial DAC options.

Digital To Analog Converters Part Context

This device belongs to the MAX551/MAX552 family of serial multiplying DACs. While the MAX551 operates at +5V, the MAX552 is optimized for +3V applications. Both share identical architecture, including the R-2R resistor array and serial interface logic. The MAX552AEUB represents the extended temperature grade of the standard MAX552ACUB.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes include the MAX552BEUB for relaxed linearity requirements (±1 LSB). Other packages such as the 8-pin DIP (MAX552AEPA) offer alternative form factors. Verify pin compatibility and thermal performance when substituting across different package types.
