MCP48CVD12-E/UN

Digital To Analog Converters Overview

The MCP48CVD12-E/UN is a single-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features volatile memory and an SPI-compatible serial interface supporting write speeds up to 50 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. Key electrical characteristics include a typical settling time of 4 µs, ±1 LSB Integral Nonlinearity (INL), and ±1 LSB Differential Nonlinearity (DNL). It offers multiple reference source options including VDD, external VREF, or an internal bandgap, along with unity or 2x gain configurations.

Digital To Analog Converters Feature Summary

• Single-channel 12-bit resolution with buffered voltage output
• SPI serial interface with high-speed write capabilities
• Flexible voltage reference selection including internal bandgap
• Extended industrial temperature range operation

Digital To Analog Converters Applications

• Set point or offset trimming in control systems
• Sensor calibration and signal conditioning
• Low-power portable instrumentation
• Data acquisition systems requiring precise analog outputs

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure that the volatile memory configuration aligns with system power-loss requirements, as data is not retained without non-volatile alternatives. Confirm compatibility with the host microcontroller's SPI mode and voltage levels before integration.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit DAC with volatile storage is sufficient for the application. Consider the MCP48CMD12 variant if non-volatile memory retention is required across power cycles. Evaluate the need for external versus internal voltage references based on precision requirements and board space constraints. Verify that the MSOP-10 package fits the design footprint.

Digital To Analog Converters Part Context

This part belongs to the MCP48CXDX family of digital-to-analog converters, which includes 8-bit, 10-bit, and 12-bit resolutions in both single and dual channel configurations. The 'V' designation indicates volatile RAM-based memory, distinguishing it from the 'M' series which utilizes Multi-Time Programmable (MTP) non-volatile memory. All variants share similar pinouts and SPI interfaces for ease of migration within the family.

Digital To Analog Converters Replacement Considerations

Public confirmed substitute part numbers are not explicitly listed in the provided datasheet. For non-volatile memory requirements, consider the MCP48CMD12-E/UN. For different resolutions, refer to the MCP48CVD11-E/UN (10-bit) or MCP48CVD01-E/UN (8-bit) within the same volatile memory family.
