MCP48CMD01T-E/MG

Overview

The MCP48CMD01T-E/MG is a single-channel, 8-bit Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory. It operates within a supply voltage range of 2.7V to 5.5V and supports an SPI serial interface with write speeds up to 50 MHz. The device provides buffered voltage outputs with selectable gain options of 1x or 2x. Key electrical specifications include a typical settling time of 4 µs, integral nonlinearity (INL) of ±1 LSB, and differential nonlinearity (DNL) of ±1 LSB. It includes power-on/brown-out reset protection and multiple power-down modes for low-power applications.

Feature Summary

• Integrated MTP memory allows user-programmable storage of DAC output values, configuration registers, and general-purpose data.
• Flexible reference voltage selection between VDD, external VREF pin, or internal band gap source.
• SPI-compatible interface supporting high-speed write operations up to 50 MHz.
• Configurable power-down modes that disconnect the output buffer or select pull-down resistors.

Applications

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

Procurement Notes

Verify the specific package marking and tape-and-reel quantity against the manufacturer's latest shipping documentation. Confirm that the ordering suffix corresponds to the required moisture sensitivity level and reel size. Ensure compatibility with the target board's soldering profile and storage conditions prior to assembly.

Selection Notes

Select this component when a single-channel 8-bit resolution is sufficient for the application. The MTP memory variant is appropriate if persistent configuration without external EEPROM is required. Verify that the 2.7V to 5.5V supply range meets system requirements and that the MSOP-10 package fits the PCB layout constraints.

Part Context

This part belongs to the MCP48CXDX1/2 family, which includes 8-bit, 10-bit, and 12-bit variants in both single and dual channel configurations. The 'CMD' designation indicates the presence of nonvolatile MTP memory, distinguishing it from volatile RAM-based versions like the CVD series. The 'MG' suffix typically denotes the MSOP-10 package type.

Replacement Considerations

Direct functional substitutes within the same family include MCP48CVD01T-E/MG (volatile memory version). Other resolutions such as MCP48CMD11T-E/MG (10-bit) or MCP48CMD21T-E/MG (12-bit) may be used if higher resolution is acceptable and pin compatibility is maintained.
