MCP47FEB02A1-E/ST

Digital To Analog Converters Overview

The MCP47FEB02A1-E/ST is a dual-channel, 8-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, with full specifications guaranteed from 2.7V to 5.5V. The device provides rail-to-rail output with a typical settling time of 6 µs. It supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I²C modes. Power consumption is low, drawing less than 380 µA in normal operation and 650 nA in power-down mode. The component is housed in an 8-lead TSSOP package and functions across an extended temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with integrated nonvolatile EEPROM for persistent DAC settings and configuration recall upon power-up or brown-out reset.
• Flexible reference input options including internal band gap, external VREF pin, or device VDD, supporting unity or 2x output gain configurations.
• Low-power design with multiple power-down modes allowing high-impedance output or selectable pull-down resistors to minimize standby current.
• Robust I²C compatibility supporting standard, fast, and high-speed communication modes with user-programmable slave addresses.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring precise analog adjustments
• Low-power portable instrumentation devices
• Motor control applications needing variable voltage references

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure the I²C address configuration matches the system requirements, as this model supports user-programmable addresses. Confirm that the selected operating voltage falls within the specified range for the desired performance specifications.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with nonvolatile storage is required to maintain output states after power loss. Consider the 8-bit resolution and 6 µs settling time for applications where moderate speed and precision are sufficient. Evaluate the power supply constraints, noting that analog performance may be reduced below 2.7V while maintaining digital functionality down to 1.8V.

Digital To Analog Converters Part Context

This part belongs to the MCP47FEBXX family of single and dual-channel DACs from Microchip Technology. The series offers 8-bit, 10-bit, and 12-bit resolutions with varying channel counts. The '02' designation indicates a dual-channel configuration with 8-bit resolution, distinguishing it from single-channel variants like the MCP47FEB01 or higher-resolution models such as the MCP47FEB12.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include other MCP47FEBxx variants with compatible pinouts and interfaces. Verify that substitute parts match the required channel count, resolution, and EEPROM functionality. Ensure the alternative component supports the necessary I²C speeds and operating voltage ranges for the specific application environment.
