MCP47CVD02-E/MF

Digital To Analog Converters Overview

The MCP47CVD02-E/MF is a dual-channel, 8-bit Digital-to-Analog Converter (DAC) from Microchip Technology. It features volatile memory and an I2C serial interface for data transmission. The device operates within a supply voltage range of 2.7V to 5.5V, with reduced specifications available between 1.8V and 2.7V. It provides buffered voltage outputs with integral nonlinearity (INL) specified at ±1 LSB. Key electrical parameters include a typical settling time of 4 µs, a maximum gain error of ±0.6% of full-scale range (FSR), and a differential nonlinearity (DNL) of ±0.1 LSB. The component supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I2C modes.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent buffered voltage outputs in a single package.
• I2C compatible serial interface supporting Standard, Fast, and High-Speed communication modes.
• Configurable reference voltage sources including VDD, external VREF pin, or internal band gap.
• Power-on/Brown-out reset protection ensures defined output states during power transitions.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring precise analog signal generation
• Low-power portable instrumentation devices
• PC peripherals and data acquisition systems

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 selected variant matches the required memory configuration, as this model utilizes volatile RAM which loses data upon power loss. Cross-reference the datasheet revision date to confirm compatibility with existing design specifications and regulatory compliance requirements.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel DAC solution is required with I2C connectivity. Consider the volatile memory characteristic, which necessitates re-initialization after power cycles. Evaluate the operating voltage range to ensure it aligns with the system's power supply rails. Verify that the I2C address configuration via physical pins meets the bus addressing requirements of the host controller.

Digital To Analog Converters Part Context

This device belongs to the MCP47CXDX family of digital-to-analog converters. It shares architectural similarities with other members such as the MCP47CMD series, which offers nonvolatile MTP memory instead of volatile RAM. The 'D' designation indicates the volatile memory option, while '02' specifies the dual-channel configuration with 8-bit resolution. This family is designed for applications requiring compact form factors and low power consumption.

Digital To Analog Converters Replacement Considerations

The MCP47CMD02-E/MF serves as a direct functional substitute if nonvolatile memory retention is required. For single-channel applications, the MCP47CVD01-E/MF may be considered. Ensure that any replacement maintains the same I2C interface protocol and voltage operating ranges to guarantee circuit compatibility without hardware modifications.
