MCP47FEB22A3-E/ST

Digital To Analog Converters Overview

The MCP47FEB22A3-E/ST is a dual-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features an I²C serial interface and integrated nonvolatile EEPROM memory for power-on reset settings. The device operates within a supply voltage range of 2.7V to 5.5V, with reduced specifications available from 1.8V to 2.7V. Key electrical parameters include a typical settling time of 6 µs, a maximum full-scale error of 70 LSBs, and a gain error of ±1.0% of FSR. It supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I²C modes.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent 12-bit DAC outputs in a single package.
• Integrated nonvolatile EEPROM memory retains DAC register settings, configuration bits, and power-down states across power cycles.
• Flexible reference voltage selection allowing operation with VDD, external VREF pin, or internal band gap source.
• Configurable output buffer gain options including unity (1x) and 2x amplification when using external references.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the I²C slave address configuration matches the system requirements, as the A3 suffix may indicate a specific factory-programmed address. Confirm RoHS compliance status through official documentation before integration into regulated assemblies.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 12-bit resolution is required alongside persistent state retention. Consider the 6 µs settling time for dynamic applications and verify that the 1.8V to 5.5V operating range aligns with the target system power rails. Evaluate the need for high-speed I²C communication up to 3.4 Mbps versus standard bus speeds.

Digital To Analog Converters Part Context

This part belongs to the MCP47FEBXX family of nonvolatile DACs, which includes 8-bit and 10-bit variants. The '22' designation specifically identifies it as a dual-channel, 12-bit resolution device. It shares common interface protocols and memory structures with other members of the series, facilitating design scalability across different channel count and resolution requirements.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include MCP47FEB12A3-E/ST (10-bit dual) and MCP47FEB02A3-E/ST (8-bit dual). Single-channel alternatives like MCP47FEB21A3-E/ST are functionally compatible but require separate addressing. Verify pinout compatibility and EEPROM endurance specifications when cross-referencing.
