MCP47CVD12T-E/UN

Digital To Analog Converters Overview

The MCP47CVD12T-E/UN is a dual-channel, 12-bit 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 provides buffered voltage outputs with Integral Nonlinearity (INL) and Differential Nonlinearity (DNL) specifications of ±1 LSB at 12-bit resolution. Key electrical parameters include a typical settling time of 4 µs, a maximum power-down current of 2.4 µA, and an operating temperature range from -40°C to +125°C. It utilizes a 10-lead MSOP package.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with 12-bit resolution and volatile RAM storage for output data retention during power cycles.
• Configurable reference voltage sources including VDD, external VREF pin, and internal band gap, supporting gain settings of 1x or 2x.
• I²C compatible serial interface supporting Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) modes.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring precise voltage references
• 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 configuration when sourcing components. Confirm that the 'E' suffix denotes the extended industrial temperature grade (-40°C to +125°C). Ensure compatibility with the required I²C clock speeds and voltage levels for the target application environment before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component for applications requiring dual independent voltage outputs with high precision (12-bit) and low nonlinearity error. Consider the volatile memory characteristic, which requires external microcontroller intervention to restore DAC values after power loss. Evaluate the power supply constraints, as analog specifications degrade below 2.7V, though digital operation continues down to 1.8V.

Digital To Analog Converters Part Context

This device belongs to the MCP47CXDX family of 8-bit, 10-bit, and 12-bit DACs. The 'V' designation specifically identifies the volatile memory variant, distinguishing it from the nonvolatile MTP-based CMD series. The dual-channel DX2 configuration allows for compact designs in space-constrained PCB layouts compared to single-channel alternatives.

Digital To Analog Converters Replacement Considerations

For nonvolatile requirements, consider the MCP47CMD12T-E/UN. For single-channel applications, the MCP47CVD12T-E/UN is available. Higher resolution options include the MCP47CVB12 series, while lower resolution variants like the MCP47CVD10 or MCP47CVD08 may offer cost benefits if precision requirements allow.
