MCP48CMD01T-E/UN

Overview

The MCP48CMD01T-E/UN 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 utilizes 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, an Integral Nonlinearity (INL) of ±1 LSB, and a Differential Nonlinearity (DNL) of ±1 LSB. The unit is housed in a 10-lead MSOP package.

Feature Summary

• Integrated MTP memory for storing DAC output values and configuration registers without external components.
• SPI-compatible serial interface supporting high-speed data transfer and standard mode configurations.
• Configurable power-down modes allowing selection between high-impedance output or internal pull-down resistors.

Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring persistent configuration storage
• Low-power portable instrumentation devices

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 target market. Cross-reference the full part number with official distributor catalogs to confirm availability status and lead times prior to finalizing procurement plans.

Selection Notes

Select this model when a single-channel DAC with nonvolatile memory retention is required. The 8-bit resolution suits applications where moderate precision is acceptable. Verify that the system logic levels are compatible with the SPI interface and that the operating temperature range aligns with the -40°C to +125°C specification.

Part Context

This component belongs to the MCP48CXDX1/2 family of digital-to-analog converters. The family includes variants with volatile RAM or nonvolatile MTP memory, and resolutions ranging from 8-bit to 12-bit. The 'CMD' designation specifically indicates the inclusion of MTP memory capabilities within the single-channel architecture.

Replacement Considerations

Direct replacements within the same family include other MCP48CMD01 variants with different packaging options such as QFN or DFN. For dual-channel requirements, consider the MCP48CMD02 series. Ensure any substitute maintains the same MTP memory functionality and SPI interface compatibility.
