MAX551BCPA

Digital To Analog Converters Overview

The MAX551BCPA 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 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 Schmitt-trigger inputs. Integral Nonlinearity (INL) is ±1 LSB, and Differential Nonlinearity (DNL) is ±1 LSB. Supply current is typically 0.5mA at VDD=5V. It is housed in an 8-pin Plastic DIP package.

Digital To Analog Converters Feature Summary

• 12-bit resolution with R-2R thin-film resistor array architecture
• Compatible with SPI, QSPI, and MICROWIRE serial interfaces
• Capable of unipolar or bipolar output operation with a single supply
• Includes internal power-on-reset circuit for zero initialization

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CPA' indicates the 8-pin Plastic DIP package variant. Confirm the operating temperature range matches the 'B' grade specification of 0°C to +70°C. Ensure the application requires a single +5V supply environment compatible with the MAX551 series electrical characteristics.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit multiplying DAC is required with a serial interface to save board space. It is suitable for applications needing unipolar or bipolar outputs from a single supply. Consider the ±1 LSB linearity limits and the need for an external amplifier if voltage output is desired instead of current.

Digital To Analog Converters Part Context

This part belongs to the MAX551/MAX552 family of low-power, serial multiplying DACs. The MAX551 variant specifically supports +5V operation, while the MAX552 supports +3V. The 'C' designation denotes the commercial temperature range, and 'P' indicates the DIP package style within the Maxim Integrated product lineup.

Digital To Analog Converters Replacement Considerations

Direct replacements include other MAX551 variants such as MAX551ACPA or MAX551BEPA, depending on the required linearity accuracy and operating temperature range.
