MCP48CMD12T-E/UN

Overview

The MCP48CMD12T-E/UN is a dual-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features Multi-Time Programmable (MTP) nonvolatile memory and an SPI serial interface. The device operates on a single supply voltage ranging from 2.7V to 5.5V, with reduced specifications available for the 1.8V to 2.7V range. Key electrical parameters include a typical settling time of 4µs, a maximum Integral Nonlinearity (INL) of ±1 LSB, and a gain error of ±0.6% of Full Scale Range (FSR). It supports reference sources including VDD, external VREF, or an internal band gap, with selectable unity or 2x gain.

Feature Summary

• Integrates MTP nonvolatile memory allowing user programming of up to 32 locations for power-up values and configuration.
• Provides dual buffered voltage outputs with selectable gain options of 1x or 2x depending on the reference source.
• Features a high-speed SPI interface supporting write speeds up to 50 MHz and read speeds up to 25 MHz.
• Includes Power-on/Brown-out Reset protection and configurable power-down modes for low-power operation.

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 multi-channel voltage references

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your region. Confirm that the LAT/HVC pin voltage handling capabilities align with your system's programming interface before finalizing procurement.

Selection Notes

Select this component when dual-channel 12-bit resolution with nonvolatile storage is required. Verify that the operating voltage range of 2.7V to 5.5V matches your system rails. Consider the 1.8V to 2.7V reduced specification mode if lower voltage operation is necessary. Ensure the SPI interface timing constraints are compatible with your microcontroller.

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 nonvolatile memory, distinguishing it from volatile RAM-based counterparts like the CVD series. The 'UN' suffix typically denotes the MSOP-10 package variant within this product line.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes listed in distributor databases include MCP48CMD12-E/MF, MCP48CVD12-E/MF, and MCP48CVD12T-E/MF. Verify package compatibility and memory type (volatile vs. nonvolatile) when substituting.
