MCP48FVB12T-E/MF

Digital To Analog Converters Overview

The MCP48FVB12T-E/MF is a dual-channel, 10-bit volatile digital-to-analog converter (DAC) manufactured by Microchip Technology. It features an SPI serial interface and R-2R architecture with voltage buffered outputs. The device operates on analog and digital supply voltages ranging from 1.8 V to 5.5 V. Key performance metrics include a settling time of 7.8 µs, differential nonlinearity (DNL) of ±0.05 LSB, integral nonlinearity (INL) of ±0.4 LSB, and total harmonic distortion (THD) of -64 dB. Gain error is specified at 0.1% FSR. It supports external, internal, or supply reference types and functions within a temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Dual-channel configuration providing independent analog output control via SPI interface
• Integrated voltage buffers for direct drive capability without external amplification
• R-2R resistor ladder architecture ensuring stable conversion characteristics
• Wide supply voltage compatibility supporting low-power and standard logic systems

Digital To Analog Converters Applications

• Sensor calibration circuits requiring precise analog signal generation
• Motor control systems needing adjustable setpoints or offset adjustments
• Instrumentation applications utilizing multi-channel data acquisition

Digital To Analog Converters Procurement Notes

Verify the specific suffix E/MF against official Microchip documentation to confirm package type and temperature grade. Ensure the volatile nature of the DAC aligns with system power-loss requirements, as settings are not retained without external EEPROM integration. Confirm SPI pin compatibility with the host controller before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 10-bit resolution is required with high linearity specifications. Compare DNL and INL values against application tolerance levels. Consider the 7.8 µs settling time for bandwidth limitations. Verify that the MSOP-10 package fits the PCB layout constraints and thermal management requirements for the intended operating environment.

Digital To Analog Converters Part Context

This part belongs to the MCP48FVBXX series of single and dual channel DACs. Unlike the MCP48FEBXX series, it lacks integrated EEPROM, making it a cost-effective solution for volatile applications. It shares the same SPI interface and MSOP-10 packaging family with other variants in the MCP48FVB line.

Digital To Analog Converters Replacement Considerations

Check for compatible substitutes within the MCP48FVB family, such as MCP48FVB11T-E/MF for single-channel use or MCP48FVB02T-E/MF for 8-bit resolution. Ensure pinout and electrical parameters match exactly when substituting.
