MCP47FVB14T-E/MQ

Digital To Analog Converters Overview

The MCP47FVB14T-E/MQ is a quad-channel, 10-bit buffered voltage output Digital-to-Analog Converter (DAC) from Microchip Technology. It features volatile RAM memory and an I2C-compatible serial interface supporting Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes. The device operates within a supply voltage range of 2.7V to 5.5V for full specifications, with reduced specifications available between 1.8V and 2.7V. It offers rail-to-rail output capability and a typical settling time of 7.8 µs. Voltage reference options include the external VREF pin, internal band gap (1.22V typical), or device VDD. The component is housed in a 20-lead VQFN package measuring 5 x 5 mm and supports an extended operating temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Quad-channel configuration providing four independent buffered voltage outputs.
• I2C compatible serial interface with support for standard, fast, and high-speed data transfer rates.
• WiperLock™ functionality utilizing high-voltage commands to prevent inadvertent changes to stored values.
• Configurable power-down modes allowing selection between high-impedance output or pull-down resistors.

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 ordering suffix against official documentation to confirm package type and temperature grade. Ensure that the selected variant matches the required channel count and memory type for the target design. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status and lead times prior to finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel DAC with I2C connectivity is required. Consider the 10-bit resolution and volatile memory characteristics for applications where power loss does not necessitate data retention. Evaluate the 2.7V to 5.5V operating range against system power constraints. Verify compatibility with the host controller's I2C speed capabilities and address configuration requirements.

Digital To Analog Converters Part Context

This model belongs to the MCP47FXBX4/8 family of digital-to-analog converters. The 'FVB' designation indicates a volatile memory version with four channels and 10-bit resolution. The 'MQ' suffix specifies the 20-lead VQFN package format. This family shares architectural similarities with octal-channel variants and nonvolatile EEPROM versions, differing primarily in channel count and memory persistence.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include other MCP47FVB14 variants with different packaging options such as TSSOP-20. For quad-channel configurations, the MCP47FVB04 or MCP47FVB24 series may be considered if resolution differences are acceptable. Nonvolatile alternatives like the MCP47FEB14 series offer similar performance with EEPROM storage.
