MAX551BCPA+

Digital To Analog Converters Overview

The MAX551BCPA+ is a 12-bit, current-output multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +4.5V to +5.25V supply and features an SPI/QSPI/MICROWIRE-compatible 3-wire serial interface with a maximum clock rate of 12.5MHz. The device includes double-buffered logic with 12-bit input and DAC registers, power-on reset, and asynchronous clear functions. It utilizes an internal R-2R resistor array and provides unipolar or bipolar output capabilities. The component is housed in an 8-pin Plastic DIP package and supports a commercial temperature range of 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Supports 4-quadrant multiplying applications with unipolar or bipolar outputs using a single power supply
• Features a high-speed 3-wire serial interface compatible with SPI, QSPI, and MICROWIRE standards
• Includes internal power-on reset and asynchronous clear inputs for reliable 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 ordering suffix 'C' indicates the commercial temperature range of 0°C to +70°C and 'B' denotes ±1 LSB linearity. Confirm the 'PA' suffix corresponds to the 8-pin Plastic DIP package configuration. Ensure compatibility with the required supply voltage range of +4.5V to +5.25V for the MAX551 variant before procurement.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution with current output is required for multiplying DAC applications. The MAX551 variant is suitable for single-supply +5V operation. Consider the 8-pin DIP package if through-hole mounting is necessary. Verify that the ±1 LSB linearity meets system accuracy requirements compared to the higher precision MAX551A variant.

Digital To Analog Converters Part Context

The MAX551BCPA+ belongs to the MAX551/MAX552 family of serial multiplying DACs. This series distinguishes itself by offering true 4-quadrant multiplication capability within a compact serial interface format. The MAX551 specifically targets +5V single-supply applications, while the MAX552 serves +3V systems. The BC part number represents a specific grade within this family focusing on standard linearity specifications.

Digital To Analog Converters Replacement Considerations

Direct replacements include other variants within the MAX551 family such as MAX551ACPA+ for improved linearity or MAX551BEPA+ for extended temperature ranges. Cross-family alternatives like the MAX535 require evaluation of pinout and interface compatibility.
