MCP47FEB22A1-E/ST

Digital To Analog Converters Overview

The MCP47FEB22A1-E/ST is a dual-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring nonvolatile EEPROM memory and an I²C serial interface. It operates within a supply voltage range of 1.8V to 5.5V, supporting Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) modes. The device provides rail-to-rail outputs with a typical settling time of 6 µs. Reference sources include the VDD supply, an external VREF pin, or an internal 1.22V band gap. It includes power-on/brown-out reset protection, user-programmable power-down modes, and operates across an extended temperature range of -40°C to +125°C in an 8-lead TSSOP package.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with integrated nonvolatile EEPROM for persistent DAC register and configuration storage.
• I²C-compatible serial interface supporting multiple clock speeds up to 3.4 Mbps.
• Configurable reference voltage selection between internal band gap, VDD, or external VREF pin.
• Rail-to-rail buffered output capability with selectable unity or 2x gain.

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 against the manufacturer's current documentation to confirm package type and temperature grade. Ensure the I²C slave address configuration matches the system requirements, as this variant supports user-programmable addresses. Confirm that the selected reference voltage source aligns with the desired output gain settings for the target application.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with nonvolatile memory retention is required. The 12-bit resolution offers 4096 steps for precise analog control. Consider the operating voltage range and the need for high-speed I²C communication. Verify that the 8-lead TSSOP package fits the available PCB space and thermal constraints.

Digital To Analog Converters Part Context

This part belongs to the MCP47FEBXX family of single and dual-channel DACs from Microchip Technology. The '22' designation indicates a dual-channel configuration with 12-bit resolution. The 'E' suffix typically denotes the extended industrial temperature range, while '/ST' specifies the 8-lead TSSOP package format.

Digital To Analog Converters Replacement Considerations

Check for other members of the MCP47FEBXX series with matching channel counts and resolutions. Verify compatibility with existing I²C addressing schemes if using programmable addresses. Ensure substitute parts support the same voltage ranges and nonvolatile memory features.
