MCP47CVB02T-E/MG

Digital To Analog Converters Overview

The MCP47CVB02T-E/MG is a dual-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) from the MCP47CXBXX family. It features volatile memory and an I2C serial interface supporting Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) modes. The device operates on a supply voltage of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. It includes Power-on/Brown-out Reset protection and power-down modes that disconnect the output buffer or select pull-down resistors. The component is housed in a 16-lead QFN package and supports an extended operating temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent buffered voltage outputs within a single integrated circuit.
• Configurable reference voltage sources including VDD, external VREF pin, and internal band gap, with selectable gain options.
• I2C compatibility with multiple speed modes and flexible slave address configuration via physical pins.
• Integrated power management features including POR/BOR protection and configurable low-power shutdown states.

Digital To Analog Converters Applications

• Set point or offset trimming in precision instrumentation circuits
• Sensor calibration systems requiring multi-channel adjustment
• Low-power portable instrumentation devices
• PC peripherals and data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging rather than tube. Confirm the '-MG' suffix corresponds to the 16-lead QFN package type as specified in the datasheet. Ensure the 'E' designation aligns with the required extended industrial temperature range. Cross-reference the manufacturer part number against official Microchip documentation to validate current production status and availability constraints.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution is required without nonvolatile storage needs. The volatile memory design suits applications where power-up defaults are managed by the host system. Consider the 8-bit resolution limits for accuracy requirements. Evaluate the I2C bus speed capabilities against system timing constraints. Verify that the QFN package footprint fits the available PCB real estate.

Digital To Analog Converters Part Context

This device belongs to the MCP47CXBXX family of digital-to-analog converters. It shares core architectural features with other members such as the MCP47CVB01 and MCP47CVB12, differing primarily in channel count and resolution. The 'CV' prefix denotes volatile memory, distinguishing it from the MTP-based MCP47CMBXX series. All variants utilize the same I2C interface protocol and similar electrical characteristics.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other dual-channel variants within the MCP47CXBXX family, such as MCP47CVB12 or MCP47CVB22, depending on resolution requirements. Single-channel alternatives like MCP47CVB01 may be used if only one output is needed. Nonvolatile equivalents in the MCP47CMBXX series require consideration of the MTP programming overhead.
