MAX551BEPA

Digital To Analog Converters Overview

The MAX551BEPA 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 frequency of 12.5MHz. The device includes double-buffered logic with separate input and DAC registers, a power-on-reset circuit, and Schmitt-trigger digital inputs. It is housed in an 8-pin Plastic DIP package and supports unipolar or bipolar output configurations.

Digital To Analog Converters Feature Summary

• Supports 4-quadrant multiplying applications using a single power supply
• Features a high-speed 3-wire serial interface compatible with standard protocols
• Includes internal power-on-reset and asynchronous clear functions for zero initialization

Digital To Analog Converters Applications

• Automatic Calibration Systems
• Process-Control I/O Boards
• Programmable Amplifiers and Attenuators

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C). Confirm the 'P' suffix corresponds to the 8-pin Plastic DIP package. Ensure compatibility with the required supply voltage range of +4.5V to +5.25V. Check for RoHS compliance status if required by local regulations.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution and multiplying capability are required in a low-pin-count DIP package. Consider the MAX551AEPA variant if a tighter linearity specification of ±1/2 LSB is needed instead of the ±1 LSB provided by the BEPA version. Evaluate the need for external feedback resistors if operating in current mode.

Digital To Analog Converters Part Context

This part belongs to the MAX551/MAX552 family of serial multiplying DACs. The MAX551 series is designed for +5V operation, while the MAX552 series supports +3V supplies. The BEPA designation specifically identifies the industrial temperature grade and through-hole packaging within this product line.

Digital To Analog Converters FAQ

Does the MAX551BEPA support bipolar output?

Yes, it can provide bipolar outputs when configured with appropriate external circuitry and reference voltages.

What is the function of the CLR pin on the DIP package?

The CLR pin is not present on the 8-pin DIP package; it is exclusive to the 10-pin µMAX package.

How does the serial interface handle data loading?

Data is shifted into the input register via DIN and SCLK, then transferred to the DAC register asynchronously by driving the LOAD input low.
