MCP4728A1-E/UN

Digital To Analog Converters Overview

The MCP4728A1-E/UN is a quad, 12-bit voltage output Digital-to-Analog Converter (DAC) featuring on-board nonvolatile memory (EEPROM). It provides four buffered analog outputs with rail-to-rail swing capability. The device operates from a single supply voltage ranging from 2.7V to 5.5V and supports Standard (100 kbps), Fast (400 kbps), and High Speed (3.4 Mbps) I2C interface modes. Key electrical specifications include a typical settling time of 6 µs, ±0.2 LSB differential nonlinearity (DNL), and an operating temperature range of -40°C to +125°C. It utilizes a 10-lead MSOP package.

Digital To Analog Converters Feature Summary

• Quad-channel architecture with individual buffered voltage outputs
• On-board EEPROM for retaining DAC codes and configuration settings during power-off
• Flexible reference selection allowing internal or external voltage reference usage per channel
• Configurable power-down modes for individual channels to optimize power consumption

Digital To Analog Converters Applications

• Set point or offset adjustment in control systems
• Sensor calibration requiring precise voltage references
• Closed-loop servo control applications
• Programmable voltage and current sources
• Bias voltage adjustment for power amplifiers

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'A1' against the manufacturer's official documentation to confirm if it denotes a distinct revision or variant compared to the standard MCP4728. Ensure that the ordering information matches the exact package type and temperature grade required for the target application environment before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a multi-channel DAC with persistent memory is required. Consider the 12-bit resolution and I2C interface compatibility with the host controller. Evaluate the power supply constraints against the 2.7V to 5.5V operating range and verify that the thermal performance fits within the specified ambient temperature limits for the intended enclosure.

Digital To Analog Converters Part Context

This part belongs to the MCP4728 family of digital-to-analog converters manufactured by Microchip Technology. The family is characterized by its integration of nonvolatile memory and multiple output channels in a compact surface-mount package, designed for applications needing reliable analog signal generation without continuous data refresh.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same product line include the MCP4728T-E/UN, which differs primarily in packaging format (tape and reel versus tube). Verify pinout compatibility and electrical specifications before substituting.
