MAX552ACUB+

Digital To Analog Converters Overview

The MAX552ACUB+ 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 an SPI/QSPI/MICROWIRE-compatible 3-wire serial interface. The device includes double-buffered logic with 12-bit input and DAC registers, power-on reset, and an asynchronous clear input. It utilizes an R-2R architecture with laser-trimmed thin-film resistors. Key electrical parameters include a maximum settling time of 1µs, ±0.5 LSB differential nonlinearity (DNL), and ±1 LSB integral nonlinearity (INL). Supply current is typically 0.4µA in shutdown mode.

Digital To Analog Converters Feature Summary

• Process-Control I/O Boards
• Digitally Controlled Filters
• Programmable Amplifiers/Attenuators

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the 'UB+' designation corresponds to the 10-pin µMAX package with lead-free/RoHS compliance. Ensure the source document matches the official Maxim Integrated datasheet revision for accurate pinout and timing specifications.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution is required with low power consumption under a single +3V supply. It is suitable for applications needing multiplying capabilities with reference voltages up to ±6V. Consider the 10-pin µMAX package for space-constrained designs requiring an asynchronous clear input not available in DIP packages.

Digital To Analog Converters Part Context

This part belongs to the MAX551/MAX552 family of serial multiplying DACs. The MAX552 variant is specifically optimized for +3V operation, whereas the MAX551 supports +5V. Both share identical pinouts and functionality but differ in supply voltage ranges and reference requirements.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same package and specification include the MAX552AEUB+ (extended temperature) and MAX552BCUB+ (standard linearity). Verify that the substitute maintains the 10-pin µMAX form factor and 12-bit resolution.

Digital To Analog Converters FAQ

Does the MAX552ACUB+ support bipolar output?

Yes, it can provide bipolar outputs when configured with external resistors for 4-quadrant multiplication.

What is the function of the CLR pin?

The CLR pin provides an asynchronous clear input that resets all DAC registers to zero when pulled to GND.

Is the output buffered?

No, the MAX552 provides a current output that requires an external operational amplifier to convert to a voltage signal.
