MCP47FVB18T-E/MQ

Digital To Analog Converters Overview

The MCP47FVB18T-E/MQ is an octal-channel, 10-bit volatile digital-to-analog converter (DAC) from Microchip Technology. It features a buffered voltage output with rail-to-rail capability and communicates via an I2C-compatible serial interface supporting Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes. The device operates on a supply voltage of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V for reduced analog performance. It offers multiple voltage reference sources including VDD, external VREF, and an internal bandgap, with selectable gain options. 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

• Octal configuration providing eight independent buffered voltage outputs within a single integrated circuit.
• WiperLock™ functionality utilizing high-voltage commands to prevent inadvertent changes to stored memory values.
• Flexible power-down modes allowing selection between high-impedance output buffer disconnect or specific pull-down resistor configurations.

Digital To Analog Converters Applications

• Set point or offset trimming in precision instrumentation
• Sensor calibration systems requiring multi-channel adjustment
• Low-power portable instrumentation
• Data acquisition systems
• Motor control applications

Digital To Analog Converters Procurement Notes

Verify the ordering suffix 'T' corresponds to the reel packaging format required for your assembly line. Confirm that the 'MQ' designation matches the 20-lead VQFN 5x5mm package specification. Ensure the 'E' suffix aligns with the extended industrial temperature range requirements. Cross-reference the datasheet revision to confirm compatibility with your design specifications.

Digital To Analog Converters Selection Notes

Select this model when eight simultaneous DAC channels are required. Choose the 10-bit resolution variant if higher precision than 8-bit is needed but 12-bit speed or cost is excessive. Verify that the volatile memory architecture meets system requirements, as data is lost upon power cycle. Consider the external VREF pin availability if precise reference voltages are necessary for the application.

Digital To Analog Converters Part Context

This component belongs to the MCP47FXBX4/8 family of digital-to-analog converters. The 'VB' designation specifically identifies the volatile RAM memory version, distinguishing it from nonvolatile EEPROM variants. The '18' indicates the 10-bit resolution and octal channel count. This family shares common electrical characteristics and interfaces across its 8-bit, 10-bit, and 12-bit resolutions.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the MCP47FXBX4/8 family based on memory type (RAM vs. EEPROM) and resolution requirements. Check for pin-compatible alternatives only if the datasheet explicitly lists them as direct replacements.
