MCP48CMD01T-E/MF

Overview

The MCP48CMD01T-E/MF is a single-channel, 12-bit Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory and an SPI serial interface. It operates on a single supply voltage ranging from 2.7V to 5.5V, with reduced specifications available between 1.8V and 2.7V. The device provides buffered voltage outputs with selectable unity or 2x gain. Key electrical parameters include a typical settling time of 4 µs, a maximum Integral Nonlinearity (INL) of ±1 LSB, and a typical supply current of 190 µA at 5.5V. It supports write speeds up to 50 MHz and read speeds up to 25 MHz.

Feature Summary

• Integrated MTP nonvolatile memory allows user programming for power-up output values and configuration, supporting up to 32 write cycles per location.
• Flexible reference input options including VDD, external VREF pin, and internal band gap voltage with selectable gain settings.
• SPI-compatible serial interface with high-speed operation and support for simultaneous latching via the LAT/HVC pin.

Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration and signal conditioning
• Low-power portable instrumentation
• Data acquisition systems

Procurement Notes

Verify the specific ordering suffix 'MF' corresponds to the 10-lead MSOP package and tape-and-reel packaging format as defined in the manufacturer's official documentation. Confirm that the '-E' designation indicates the extended temperature range specification (-40°C to +125°C). Ensure compatibility with system voltage levels and SPI timing requirements before integration.

Selection Notes

Select this component when nonvolatile storage of DAC codes is required without external EEPROM. The 12-bit resolution and 1 LSB INL make it suitable for precision applications. Consider the MTP write limit of 32 cycles for field updates. Verify that the 10-lead MSOP package fits the PCB layout constraints and that the SPI interface speed meets the system data throughput needs.

Part Context

This part belongs to the MCP48CXDX1/2 family of digital-to-analog converters. The family includes variants with volatile RAM or nonvolatile MTP memory, single or dual channels, and resolutions of 8, 10, or 12 bits. The MCP48CMD01T-E/MF specifically denotes the single-channel, 12-bit, MTP-enabled version in the MSOP package.

Replacement Considerations

Direct replacements within the same family include MCP48CVD01T-E/MF (volatile memory) or MCP48CMD11T-E/MF (10-bit resolution). Cross-family alternatives like the MCP4921 series offer similar performance but may differ in package availability or specific memory features.
