MCP48CVD12-E/MF

Digital To Analog Converters Overview

The MCP48CVD12-E/MF is a dual-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) from Microchip Technology. It features volatile memory and an SPI-compatible serial interface supporting write speeds up to 50 MHz and read speeds up to 25 MHz. The device operates on a single supply voltage ranging from 2.7V to 5.5V, with reduced specifications available for the 1.8V to 2.7V range. It offers integral nonlinearity of ±1 LSB and differential nonlinearity of ±1 LSB. Reference options include device VDD, external VREF, or an internal bandgap of 1.214V typical. The DAC provides unity or 2x gain options and includes power-down modes for low-power applications.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with 12-bit resolution and buffered voltage outputs
• SPI serial interface with high-speed write and read capabilities
• Multiple reference source selections including internal bandgap and external pin
• Configurable power-down modes with selectable pull-down resistors

Digital To Analog Converters Applications

• Set point or offset trimming in industrial systems
• Sensor calibration requiring precise analog adjustments
• Low-power portable instrumentation devices
• Data acquisition systems needing multi-channel conversion

Digital To Analog Converters Procurement Notes

Verify the specific package variant, as the E/MF suffix denotes a 10-lead MSOP package. Confirm that the volatile memory type aligns with system requirements, as data is lost upon power removal. Ensure the LAT/HVC pin handling meets programming needs if MTP features are utilized in related family members, though this specific part uses RAM. Check operating voltage compatibility with the target application's power rails.

Digital To Analog Converters Selection Notes

Select this component when dual-channel 12-bit precision is required with SPI connectivity. Consider the MCP48CMD12 series if nonvolatile memory retention is necessary for power-cycle persistence. Evaluate the 1.8V to 2.7V operating range limitations if using lower supply voltages, as analog specifications may be reduced. Ensure the 10-lead MSOP package fits the PCB layout constraints compared to QFN or DFN alternatives.

Digital To Analog Converters Part Context

This device belongs to the MCP48CXDX1/2 family, which encompasses single and dual channel DACs with resolutions of 8, 10, and 12 bits. The 'V' in the model number indicates volatile memory, distinguishing it from the 'M' suffix parts that feature Multi-Time Programmable (MTP) nonvolatile memory. All variants share similar electrical characteristics and interface protocols, differing primarily in memory type and channel count.

Digital To Analog Converters Replacement Considerations

MCP48CMD12-E/MF: Identical electrical performance but includes nonvolatile MTP memory instead of volatile RAM.

Digital To Analog Converters FAQ

What is the maximum SPI clock speed for writing data?

The device supports a write speed of up to 50 MHz.

Can the gain be set to 2x when using the internal bandgap reference?

No, the 2x gain option is only available when not using the internal VDD as the voltage source; typically, this requires an external VREF pin.

How does the device handle power-on reset conditions?

The device includes Power-on/Brown-out Reset (POR/BOR) protection, ensuring stable operation during power transitions.
