MCP47CVD11-E/UN

Digital To Analog Converters Overview

The MCP47CVD11-E/UN is a single-channel, 10-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring volatile memory and an I2C serial interface. It operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. The device supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I2C modes. Key electrical characteristics include a typical settling time of 4 µs, a maximum Integral Nonlinearity (INL) of ±0.25 LSB, and a maximum Differential Nonlinearity (DNL) of ±0.25 LSB. It offers reference voltage options including VDD, external VREF, or an internal band gap.

Digital To Analog Converters Feature Summary

• Single-channel buffered voltage output with 10-bit resolution providing 1024 distinct steps.
• I2C compatible serial interface supporting Standard, Fast, and High-Speed communication modes.
• Flexible DAC voltage reference source selection among device VDD, external VREF pin, or internal band gap.
• Configurable power-down modes allowing output buffer disconnection or selection of pull-down resistors.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration requiring precise voltage references
• Low-power portable instrumentation devices
• PC peripherals managing analog signal generation

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure the design accommodates the volatile memory nature, as data is lost upon power removal. Confirm I2C address configuration requirements based on the selected physical address pins for the specific package variant.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 10-bit DAC with I2C connectivity is required. Consider the MCP47CMD11 if nonvolatile MTP memory retention across power cycles is necessary. Evaluate the operating voltage range carefully, as specifications degrade below 2.7V. Verify that the external load conditions align with the specified settling time and output drive capabilities.

Digital To Analog Converters Part Context

This part belongs to the MCP47CXDX family of digital-to-analog converters. It shares architectural similarities with other variants in the series, differing primarily in channel count, resolution, and memory type. The 'V' designation indicates volatile RAM storage, while 'D1' specifies the 10-bit resolution and single-channel configuration within the broader product line.

Digital To Analog Converters Replacement Considerations

MCP47CMD11-E/UN: Offers identical electrical performance but includes nonvolatile MTP memory for data retention.

Digital To Analog Converters FAQ

What happens to the DAC output value after a power cycle?

Since the MCP47CVD11-E/UN utilizes volatile memory, the DAC output reverts to the factory default Power-on Reset (POR) value upon power restoration. User-defined values are not retained without external backup.

Can the internal band gap voltage be used as the reference?

Yes, the device allows selection of the internal band gap (typically 1.214V) as the voltage reference source. This option is available when using the VREF pin configuration.

What is the maximum I2C clock speed supported?

The device supports High-Speed mode with an I2C clock frequency of up to 3.4 Mbps, in addition to Standard (100 kbps) and Fast (400 kbps) modes.
