MCP47CVD12-E/UN

Digital To Analog Converters Overview

The MCP47CVD12-E/UN is a dual-channel, 12-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, with reduced analog specifications available from 1.8V to 2.7V. The device provides integral nonlinearity (INL) of ±1 LSB and differential nonlinearity (DNL) of ±1 LSB. Key electrical parameters include a typical settling time of 4 µs, a -3 dB bandwidth of 270 kHz, and a total harmonic distortion of -76 dB. It 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 with independent buffered voltage outputs
• I²C compatible serial interface supporting multiple clock speeds
• Configurable reference voltage sources including internal band gap
• Power-on/Brown-out reset protection mechanisms

Digital To Analog Converters Applications

• Set point or offset trimming in industrial systems
• Sensor calibration circuits
• Low-power portable instrumentation
• PC peripherals requiring analog signal generation
• 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 volatile memory characteristic aligns with system power-loss requirements, as data will not be retained without external backup. Cross-reference the pinout diagram for the MSOP-10 package to validate PCB layout compatibility before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when dual-channel precision is required alongside low power consumption. The 12-bit resolution offers high accuracy suitable for sensitive applications. Consider the internal band gap reference if external components must be minimized. Verify that the operating voltage range matches the system's power supply rails, noting that performance metrics may vary between the 1.8V–2.7V and 2.7V–5.5V ranges.

Digital To Analog Converters Part Context

This device belongs to the MCP47CXDX family, which includes single and dual channel variants with 8, 10, and 12-bit resolutions. The 'V' designation indicates volatile memory, distinguishing it from the 'M' series which features multi-time programmable (MTP) nonvolatile memory. All members share similar electrical characteristics and interface protocols, differing primarily in channel count and storage type.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include MCP47CVD11-E/UN (10-bit) and MCP47CVD02-E/UN (8-bit). For nonvolatile alternatives, consider the MCP47CMD12-E/UN. Ensure that any replacement maintains the dual-channel configuration and I²C interface compatibility.
