MCP48CVD01-E/UN

Digital To Analog Converters Overview

The MCP48CVD01-E/UN is a single-channel, 8-bit Digital-to-Analog Converter (DAC) featuring volatile memory and an SPI serial interface. It operates within a supply voltage range of 2.7V to 5.5V for full specifications, with reduced analog specifications available between 1.8V and 2.7V. The device provides buffered voltage outputs with selectable reference sources including VDD, external VREF, or an internal band gap. Key electrical parameters include a typical settling time of 4 µs, a maximum SPI write speed of 50 MHz, and an operating temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Utilizes volatile RAM for DAC register storage, requiring power to maintain output values.
• Supports multiple voltage reference configurations via VDD, external pin, or internal band gap.
• Features a high-speed four-wire SPI interface compatible with standard modes.
• Includes power-down modes that disconnect the output buffer or engage pull-down resistors.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring precise voltage adjustment
• Low-power portable instrumentation devices
• PC peripheral interfaces needing digital-to-analog conversion

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'E/UN' corresponds to the MSOP-10 package and extended temperature grade during sourcing. Confirm that the volatile memory characteristic aligns with system requirements for power-loss data retention. Ensure the ordering documentation matches the Microchip Technology manufacturer identification for quality assurance.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 8-bit resolution is sufficient for the application's accuracy needs. Consider the volatile memory type if power-up state initialization is handled by the host microcontroller. Evaluate the 1.8V to 2.7V reduced specification range if operating at lower supply voltages to ensure performance meets design constraints.

Digital To Analog Converters Part Context

This part belongs to the MCP48CXDX1/2 family of 8, 10, and 12-bit DACs. The 'CV' designation indicates volatile memory, distinguishing it from the 'CMD' series which includes nonvolatile MTP memory. The 'D01' suffix specifies the single-channel, 8-bit configuration within the broader product line.

Digital To Analog Converters Replacement Considerations

MCP48CVD11-E/UN offers 10-bit resolution with identical packaging and interface. MCP48CVD21-E/UN provides 12-bit resolution for higher precision needs. MCP48CMD01-E/UN replaces volatile memory with nonvolatile MTP storage while maintaining the same pinout and electrical characteristics.
