MCP47CMD12T-E/UN

Digital To Analog Converters Overview

The MCP47CMD12T-E/UN is a single-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory and an I2C serial interface. It operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. The device provides a typical settling time of 4µs and supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I2C modes. It includes power-on/brown-out reset protection, configurable power-down modes, and selectable reference sources including VDD, external VREF, or an internal band gap.

Digital To Analog Converters Feature Summary

• Integrates MTP nonvolatile memory allowing up to 32 user writes per register for persistent configuration and data storage.
• Offers flexible DAC voltage reference options utilizing the device supply voltage, an external pin, or an internal band gap source.
• Supports multiple I2C communication speeds including Standard, Fast, and High-Speed modes for versatile system integration.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration requiring precise voltage references
• Low-power portable instrumentation devices
• PC peripherals requiring digital-to-analog signal conversion

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'T' indicates tape and reel packaging when sourcing components. Confirm that the '-E' suffix corresponds to the extended temperature grade (-40°C to +125°C). Ensure compatibility with the required I2C address configuration and voltage levels before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component for applications requiring a single-channel 12-bit resolution with nonvolatile memory retention. Consider the 1 LSB INL specification for high-precision requirements. Evaluate the power consumption against the available supply voltage range, noting that reduced specifications apply below 2.7V. Verify package availability matches the PCB layout constraints for the MSOP-10 form factor.

Digital To Analog Converters Part Context

This device belongs to the MCP47CXDX family of 8, 10, and 12-bit DACs from Microchip Technology. It shares architectural similarities with volatile memory variants like the MCP47CVD series but distinguishes itself through integrated MTP storage. The family supports both single and dual channel configurations across various packages including QFN, DFN, and MSOP.

Digital To Analog Converters Replacement Considerations

Direct replacements include other members of the MCP47CXDX family such as the MCP47CMD12A-E/UN or MCP47CMD12-E/ML, provided the package type and memory characteristics align with design requirements. Cross-reference datasheets for pinout compatibility and electrical parameter differences.
