MCP47FEB01A1T-E/ST

Digital To Analog Converters Overview

The MCP47FEB01A1T-E/ST is a single-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features nonvolatile EEPROM memory and an I2C serial interface supporting Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) modes. The device operates within a supply voltage range of 1.8V to 5.5V and provides rail-to-rail output with a typical settling time of 6 µs. It includes power-on/brown-out reset protection, low-power consumption, and an extended operating temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrated nonvolatile EEPROM memory for persistent storage of DAC settings and configuration bits across power cycles.
• Configurable voltage reference sources including internal band gap, external VREF pin, or device VDD.
• Supports multiple I2C communication speeds up to 3.4 Mbps with programmable slave addresses.
• Low power operation with distinct normal and power-down current modes.

Digital To Analog Converters Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation
• PC peripherals
• Data acquisition systems

Digital To Analog Converters Procurement Notes

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

Digital To Analog Converters Selection Notes

Select this component for applications requiring a single-channel DAC with nonvolatile memory retention. The 8-bit resolution offers 256 steps suitable for moderate precision tasks. Consider the available reference options and gain settings to match the desired output voltage range. Verify that the TSSOP-8 package fits the board layout constraints.

Digital To Analog Converters Part Context

This part belongs to the MCP47FEBXX family of single and dual-channel DACs. It shares core architecture with other resolutions like the 10-bit MCP47FEB1X and 12-bit MCP47FEB2X variants. The primary distinction lies in the resolution and corresponding DAC register size, while maintaining identical interface and memory features.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other MCP47FEB0X variants with different packaging or temperature grades. Cross-family replacements require matching I2C interface, resolution, and nonvolatile memory requirements.

Digital To Analog Converters FAQ

What are the available voltage reference options?

The device supports three reference sources: the internal band gap voltage (typically 1.22V), the external VREF pin (buffered or unbuffered), or the device VDD supply.

How does the device handle power loss?

The integrated EEPROM automatically recalls saved DAC register settings and device configuration bits upon power-up, ensuring consistent behavior after brown-out or power cycles.

What is the maximum I2C clock frequency?

The device supports High-Speed mode with an I2C clock frequency of up to 3.4 Mbps, in addition to Standard (100 kbps) and Fast (400 kbps) modes.
