MCP4728-E/UN

Digital To Analog Converters Overview

The MCP4728-E/UN is a quad, 12-bit voltage output Digital-to-Analog Converter (DAC) featuring on-board nonvolatile memory (EEPROM). It operates from a single 2.7V to 5.5V supply and includes four buffered analog outputs with rail-to-rail swing. The device supports I2C communication in Standard (100 kbps), Fast (400 kbps), and High Speed (3.4 Mbps) modes. Key electrical parameters include a typical settling time of 6 µs, ±0.2 LSB typical DNL, and an operating temperature range of -40°C to +125°C. Each channel allows individual selection of internal or external reference voltages.

Digital To Analog Converters Feature Summary

• Integrated EEPROM storage for DAC codes and I2C address bits
• Four independent buffered voltage outputs with rail-to-rail capability
• Flexible reference voltage selection between internal and external sources
• Support for standard, fast, and high-speed I2C serial interfaces

Digital To Analog Converters Applications

• Set point or offset adjustment
• Sensor calibration
• Closed-loop servo control
• Low power portable instrumentation
• Programmable voltage and current source

Digital To Analog Converters Procurement Notes

Verify the component manufacturer is Microchip Technology and confirm the specific part number matches MCP4728-E/UN. Ensure the package type corresponds to the 10-lead MSOP configuration. Check that the datasheet revision aligns with DS22187E. Confirm environmental compliance status such as RoHS if required by the design specifications.

Digital To Analog Converters Selection Notes

Select this component when multiple precise analog outputs are required within a compact footprint. The integrated EEPROM eliminates the need for external memory to retain settings during power cycles. Consider the internal reference stability for applications requiring moderate precision without external components. Verify that the I2C bus speed requirements match the supported Standard, Fast, or High Speed modes.

Digital To Analog Converters Part Context

This device belongs to the MCP4728 family of quad digital-to-analog converters. It shares core functionality with variants like the MCP4728A0-E/UN but differs in specific addressing or packaging details. The E suffix typically denotes extended industrial temperature ranges. It serves as a multi-channel solution for systems needing programmable analog signals controlled via a two-wire interface.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include MCP4728A0-E/UN. Verify pin compatibility and EEPROM retention features before substitution. Ensure the replacement maintains the 12-bit resolution and I2C interface requirements.
