MCP48CVD12T-E/MG

Digital To Analog Converters Overview

The MCP48CVD12T-E/MG is a dual-channel, 12-bit Digital-to-Analog Converter (DAC) featuring volatile memory and an SPI serial interface. It operates within a supply voltage range of 2.7V to 5.5V, with reduced specifications available for the 1.8V to 2.7V range. The device provides buffered voltage outputs with integral nonlinearity (INL) and differential nonlinearity (DNL) specifications of ±1 LSB. Reference sources include VDD, external VREF, or an internal band gap. It supports gain settings of 1x or 2x and includes power-down modes. The component is housed in a 16-lead QFN package measuring 3 x 3 mm and functions across an extended temperature range of -40°C to +125°C.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and tape/reel configuration. Ensure the selected variant matches the required operating voltage and memory characteristics. Cross-reference the datasheet revision date to confirm electrical parameter validity. Confirm compliance with RoHS directives prior to integration into final assemblies.

Digital To Analog Converters Selection Notes

Select this model when dual-channel conversion with high precision is required without persistent data retention needs. The volatile memory design suits applications where power-up defaults are managed by the host system. Verify that the 12-bit resolution meets the system's accuracy requirements and that the SPI interface timing aligns with the microcontroller capabilities.

Digital To Analog Converters Part Context

This component belongs to the MCP48CXDX family of digital-to-analog converters. It shares architectural similarities with single-channel variants and nonvolatile MTP versions within the same series. The 'V' designation specifically indicates volatile RAM-based registers, distinguishing it from devices with multi-time programmable memory. It complements other Microchip data converter solutions for mixed-signal designs.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same family include MCP48CVD12-E/MG and MCP48CVD12-E/ML. Single-channel equivalents such as MCP48CVD12-E/MS may require circuit redesign. Nonvolatile alternatives like MCP48CMD12T-E/MG offer similar performance but retain data upon power loss.
