MCP47CVD02T-E/MG

Digital To Analog Converters Overview

The MCP47CVD02T-E/MG is a dual-channel, 12-bit Digital-to-Analog Converter (DAC) from Microchip Technology. It features volatile memory and an I2C serial interface supporting Standard (100 kHz), Fast (400 kHz), High-Speed (1.7 MHz), and Ultra-High-Speed (3.4 MHz) modes. The device operates on a supply voltage of 2.7V to 5.5V with full specifications, or 1.8V to 2.7V with reduced analog performance. It provides buffered voltage outputs with selectable reference sources including VDD, external VREF, or an internal bandgap. Key electrical parameters include a typical settling time of 4 µs, ±1 LSB Integral Nonlinearity (INL), and ±1 LSB Differential Nonlinearity (DNL). The component is housed in a 16-lead QFN package.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing independent buffered voltage outputs for simultaneous signal generation.
• I2C compatible serial interface enabling communication across multiple speed grades up to 3.4 Mbps.
• Flexible voltage reference configuration allowing selection between device supply, external pins, or internal bandgap.
• Integrated power-on and brown-out reset protection to ensure reliable initialization.

Digital To Analog Converters Applications

• Set point or offset trimming in precision instrumentation
• Sensor calibration systems requiring multi-channel adjustment
• Low-power portable instrumentation devices
• Data acquisition systems needing buffered analog outputs

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm that the '-E' suffix corresponds to the extended industrial temperature range requirements of your design. Ensure compatibility with the 16-lead QFN footprint during PCB layout review. Cross-reference the datasheet revision to confirm pinout consistency before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this model specifically for applications requiring two independent 12-bit channels within a compact surface-mount package. Consider the volatile memory characteristic, which necessitates reprogramming upon power cycles if output retention is required. Evaluate the I2C address configuration options provided by the A0 and A1 pins to ensure proper bus addressing in multi-device systems.

Digital To Analog Converters Part Context

This component belongs to the MCP47CXDX family of digital-to-analog converters. It shares architectural similarities with single-channel variants like the MCP47CVD01 and nonvolatile counterparts such as the MCP47CMD02. The primary distinction lies in its dual-channel capability and volatile storage, differentiating it from the single-output MCP47CVD01 and the persistent-memory MCP47CMD02.

Digital To Analog Converters Replacement Considerations

For direct functional substitution, consider the MCP47CVD02 without the 'T' suffix if tube packaging is preferred. Single-channel designs may utilize the MCP47CVD01. For nonvolatile requirements, the MCP47CMD02 series offers equivalent electrical performance with persistent memory storage capabilities.
