MCP47FEB22A0-E/ST

Digital To Analog Converters Overview

The MCP47FEB22A0-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, with full specifications guaranteed from 2.7V to 5.5V. The device provides rail-to-rail outputs with a typical settling time of 6 µs. Reference options include the internal band gap (1.22V), VDD, or an external VREF pin. It supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I²C modes.

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 selected variant matches the required channel count and resolution for the target application design.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with persistent output states is required. Consider the 12-bit resolution and I²C interface compatibility with the host controller. Evaluate the operating voltage range and temperature specifications against the environmental conditions of the final assembly.

Digital To Analog Converters Part Context

This part belongs to the MCP47FEBXX family of nonvolatile DACs manufactured by Microchip Technology. The family includes single and dual-channel variants with 8-bit, 10-bit, and 12-bit resolutions. All members share the same core architecture featuring EEPROM storage and I²C connectivity.

Digital To Analog Converters Replacement Considerations

Check for other MCP47FEBXX variants with matching channel counts and resolutions. Verify pinout compatibility if substituting with different package types within the same series.

Digital To Analog Converters FAQ

What are the available voltage reference sources for the MCP47FEB22A0?

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

Does the MCP47FEB22A0 retain its output setting after power loss?

Yes, the device features nonvolatile EEPROM that stores the DAC output setting, allowing it to automatically recall the saved value upon power-up or brown-out reset.

What is the maximum I²C clock frequency supported?

The device supports Standard mode (100 kbps), Fast mode (400 kbps), and High-Speed mode (up to 3.4 Mbps).
