MCP48CMD12T-E/MG

Overview

The MCP48CMD12T-E/MG is a dual-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory. It operates on a single supply voltage ranging from 2.7V to 5.5V and supports an SPI serial interface with write speeds up to 50 MHz. The device includes an internal bandgap reference of 1.214V typical, selectable gain options of 1x or 2x, and power-down modes for low-power applications. It offers 1 LSb Integral Nonlinearity (INL), a settling time of 4 µs, and is available in a 16-lead QFN package.

Feature Summary

• Integrates MTP nonvolatile memory for retaining DAC output values and configuration registers across power cycles.
• Provides high accuracy with a 1 LSb INL specification and low differential nonlinearity error.
• Supports flexible reference sources including VDD, external VREF, or the internal bandgap voltage.
• Features a high-speed SPI interface compatible with standard modes and simultaneous latch capabilities.

Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration requiring precise analog signal generation
• Low-power portable instrumentation devices
• Data acquisition systems needing buffered voltage outputs

Procurement Notes

Verify the specific package suffix 'MG' against official Microchip documentation, as standard datasheets list MSOP, DFN, and QFN packages. Confirm availability through authorized distributors and ensure compliance with RoHS standards. Check for any recent Product Change Notices regarding packaging or material composition updates before finalizing procurement orders.

Selection Notes

Select this component when nonvolatile storage of DAC states is required without external EEPROMs. Ensure the application voltage stays within the 2.7V to 5.5V range for full specifications. Consider the 16-lead QFN package if space constraints allow; otherwise, verify if alternative suffixes like MF or ML are suitable for the PCB layout requirements.

Part Context

This part belongs to the MCP48CXDX1/2 family, which includes single and dual channel variants with 8, 10, and 12-bit resolutions. The 'CMD' designation indicates the inclusion of MTP memory, distinguishing it from volatile 'CVD' counterparts. The family shares common electrical characteristics and SPI interfaces, allowing for pin-compatible upgrades between resolution levels.

Replacement Considerations

For volatile memory requirements, consider the MCP48CVD12T-E/MG. For single-channel applications, the MCP48CMD12T-E/MG may be replaced by the MCP48CMD11T-E/MG. Verify package compatibility when substituting with other suffixes within the same resolution class.
