MCP48FVB02T-E/MF

Digital To Analog Converters Overview

The MCP48FVB02T-E/MF is a dual-channel, 8-bit volatile digital-to-analog converter (DAC) manufactured by Microchip Technology. It features an SPI serial interface and voltage buffered outputs with an R-2R resistor ladder structure. 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 ±0.0125 LSB, integral nonlinearity (INL) of ±0.1 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 an industrial temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing independent voltage buffered outputs for simultaneous signal generation.
• SPI-compatible serial interface enabling straightforward integration with microcontrollers and digital systems.
• Integrated R-2R resistor ladder network ensures stable analog output conversion without requiring external components.

Digital To Analog Converters Applications

• Sensor calibration circuits requiring precise analog offset adjustments.
• Industrial instrumentation systems needing setpoint control.
• Motor control applications utilizing low-resolution analog feedback loops.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'MF' against the official Microchip datasheet to confirm the MSOP-10 package variant and reel packaging configuration. Ensure compatibility with system voltage levels between 1.8 V and 5.5 V. Confirm that the volatile nature of the DAC aligns with application requirements, as settings are lost upon power loss. Validate thermal specifications for operation up to +125°C if used in high-temperature environments.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution is required for cost-sensitive applications lacking EEPROM storage needs. Compare against the MCP48FVB12 series for higher resolution options or the MCP48FEB series if non-volatile memory retention is necessary. Ensure the 8-bit resolution meets the precision requirements of the target application, considering the specified DNL and INL limits.

Digital To Analog Converters Part Context

This part belongs to the MCP48FVBXX family of single and dual channel DACs. It complements the MCP48FEBXX series, which includes integrated EEPROM for non-volatile storage. The VB series offers a lower-cost alternative for designs where power-down state retention is not critical. It shares the same pinout and interface characteristics as other devices in the 8/10/12-bit volatile DAC lineup.

Digital To Analog Converters Replacement Considerations

The MCP48FVB02-E/UN is a tube-packaged equivalent with identical electrical specifications. For higher resolution needs, consider the MCP48FVB12T-E/MF (10-bit) or MCP48FVB22T-E/MF (12-bit). If non-volatile storage is required, the MCP48FEB02T-E/MF provides similar functionality with integrated EEPROM.
