MAX552BCUB

Digital To Analog Converters Overview

The MAX552BCUB+ 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 and features a 3-wire serial interface compatible with SPI/QSPI and MICROWIRE standards. The device includes double-buffered logic with a 12-bit input register and DAC register. Key electrical parameters include a maximum differential nonlinearity of ±1 LSB and integral nonlinearity of ±1 LSB. Supply voltage ranges from +2.7V to +3.6V, with a typical supply current of 0.4µA in shutdown mode. It is housed in a 10-pin µMAX package.

Digital To Analog Converters Feature Summary

• Supports unipolar or bipolar output configurations using a single power supply.
• Features an asynchronous clear input that resets all DAC registers to zero upon activation.
• Includes an internal power-on-reset circuit to initialize the DAC output to zero during startup.

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 suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the '+' suffix denotes lead-free and RoHS compliance status as per manufacturer specifications. Ensure the ordering code matches the exact package type required for your PCB layout constraints.

Digital To Analog Converters Selection Notes

Select this component when a low-power, 12-bit resolution is required for single-supply applications. The MAX552 variant is specifically designed for +3V operation, distinguishing it from the MAX551 which supports +5V. Consider the 10-pin µMAX package size if board space is limited compared to standard DIP options.

Digital To Analog Converters Part Context

This part belongs to the MAX551/MAX552 family of serial multiplying DACs. While electrically similar to the MAX551, the MAX552 is optimized for lower voltage operation at +3V. The BCUB designation specifies the B grade linearity performance within the commercial temperature range and the µMAX surface-mount package format.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include MAX552ACUB+ for higher linearity grades or MAX552AEUB+/MAX552BEUB+ for extended industrial temperature ranges (-40°C to +85°C). Verify pin compatibility and thermal requirements before swapping between these variants.

Digital To Analog Converters FAQ

What is the function of the CLR pin on the MAX552BCUB?

The CLR pin provides an asynchronous clear function. When pulled to GND, it clears all DAC registers, setting the output voltage to 0V immediately.

Can the MAX552 operate with a negative reference voltage?

Yes, the MAX552 is a true 4-quadrant multiplying DAC. It accepts reference voltages ranging from -6V to +6V, allowing for bipolar output operation even with a single positive supply.

How does the serial interface handle data loading?

Data is loaded into a 12-bit input register via the serial interface. An active-low LOAD signal then transfers this data asynchronously to the DAC register, updating the output.
