MCP48CMD12T-E/MF

Overview

The MCP48CMD12T-E/MF is a dual-channel, 10-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 1.8V to 5.5V. Key electrical specifications include a typical settling time of 4µs, maximum Integral Nonlinearity (INL) of ±0.25 LSB, and maximum Differential Nonlinearity (DNL) of ±0.25 LSB. It supports power-down modes and offers selectable gain options.

Feature Summary

• Integrates MTP nonvolatile memory for retaining configuration and output values across power cycles.
• Provides dual buffered voltage outputs with selectable unity or 2x gain settings.
• Supports multiple reference sources including VDD, external VREF, and internal band gap.
• Features low-power operation with configurable power-down modes.

Applications

• Set point or offset trimming in industrial systems
• Sensor calibration circuits
• Low-power portable instrumentation
• Data acquisition systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure the design accounts for the high-voltage requirement on the LAT/HVC pin if MTP programming is utilized. Confirm compatibility with system voltage levels before integration.

Selection Notes

Select this component when dual-channel 10-bit resolution with nonvolatile storage is required. Consider the 10-lead DFN package for space-constrained designs. Evaluate the need for MTP programming capabilities versus volatile alternatives like the MCP48CVD12 series based on power-up state requirements.

Part Context

This part belongs to the MCP48CXDX1/2 family, which includes 8-bit, 10-bit, and 12-bit variants in single and dual channel configurations. The 'CMD' designation indicates the presence of MTP memory, distinguishing it from the volatile 'CVD' series within the same product line.

Replacement Considerations

The MCP48CMD12-E/MF is a parameter-equivalent alternative available in tube packaging instead of tape and reel. Other family members such as the MCP48CVD12T-E/MF offer similar performance but with volatile memory instead of nonvolatile MTP storage.
