MCP47FEB02A3-E/ST

Digital To Analog Converters Overview

The MCP47FEB02A3-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 and supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) communication modes. The device provides rail-to-rail outputs with a typical settling time of 6 µs. It includes power-on/brown-out reset protection, programmable power-down modes, and an extended operating temperature range from -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 events.
• Flexible reference input options including external VREF pin, internal bandgap voltage, or device VDD, supporting selectable unity or 2x output buffer gain.
• I²C-compatible serial interface allowing user-programmable slave addresses and operation in Standard, Fast, and High-Speed modes.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'A3' against official Microchip documentation to confirm the exact factory-set slave address and any unique manufacturing lot codes. Ensure the TSSOP-8 package dimensions match the target PCB footprint requirements. Confirm that the selected component meets the required environmental specifications for the intended application environment.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with nonvolatile storage is required to maintain output states across power cycles. Consider the 8-bit resolution and 6 µs settling time for applications where moderate precision and speed are sufficient. Evaluate the I²C bus load and available address space if multiple devices are used on the same bus.

Digital To Analog Converters Part Context

This part belongs to the MCP47FEBXX family of single and dual-channel DACs. It shares core architectural features with other members like the MCP47FEB01 and MCP47FEB12, differing primarily in channel count and resolution. The family is designed for low-cost, low-power applications requiring simple serial control and data retention without external memory components.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other members of the MCP47FEBXX series such as the MCP47FEB01 (single channel) or MCP47FEB12 (dual channel, 10-bit). Verify pin compatibility and software register mapping before substitution. Cross-reference with MCP47FVBXX series if volatile memory is acceptable.
