MCP47FVB28-E/MQ

Digital To Analog Converters Overview

The MCP47FVB28-E/MQ is an octal-channel, 12-bit Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features a VQFN-20 package and communicates via an I²C interface. The device operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. It utilizes volatile RAM memory for DAC register storage. Key electrical parameters include a typical settling time of 7.8 µs, a maximum gain error of ±1.0% FSR, and a total unadjusted error of up to +8.0 LSBs at 12-bit resolution.

Digital To Analog Converters Feature Summary

• Octal output channel configuration providing eight independent buffered voltage outputs.
• I²C serial interface supporting Standard, Fast, and High-Speed modes with user-programmable slave addresses.
• WiperLock™ functionality utilizing high-voltage commands on the LAT pin to prevent inadvertent output changes.
• Multiple voltage reference source options including internal band gap, external VREF pin, and device VDD.

Digital To Analog Converters Applications

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

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 memory type, as this model uses volatile RAM rather than nonvolatile EEPROM. Cross-reference the datasheet revision number to confirm compatibility with current design specifications.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated analog outputs are required from a single controller. The octal configuration reduces board space compared to discrete solutions. Verify that the system power supply remains within the 2.7V to 5.5V range to maintain full specification compliance. Consider the I²C address limitations if multiple devices share the same bus.

Digital To Analog Converters Part Context

This part belongs to the MCP47FXBX4/8 family of buffered voltage output DACs. The '28' designation indicates an octal channel count with 12-bit resolution. The 'FVB' series specifically denotes volatile RAM memory, distinguishing it from the 'FEB' series which includes nonvolatile EEPROM. The 'MQ' suffix identifies the 20-lead VQFN package.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include other MCP47FXBX8 variants with different resolutions (e.g., MCP47FVB18 or MCP47FVB08). For nonvolatile requirements, consider the MCP47FEB28 series. Ensure any substitute maintains the same VQFN-20 footprint and I²C protocol compatibility.
