MCP48CMB24T-E/ML

Overview

The MCP48CMB24T-E/ML is a quad-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory. It operates on a supply voltage range of 2.7V to 5.5V for full specifications and supports serial communication via an SPI interface with write speeds up to 50 MHz. The device integrates an internal bandgap reference, offers selectable gain options of 1x or 2x, and includes power-on/brown-out reset protection. It is housed in a 20-lead QFN package and rated for extended industrial temperatures from -40°C to +125°C.

Feature Summary

• Integrates MTP nonvolatile memory allowing user-programmable storage of DAC output values and configuration registers.
• Provides buffered voltage outputs with selectable gain settings of unity or double.
• Supports multiple voltage reference sources including device VDD, external VREF, and an internal bandgap.
• Features low-power operation with configurable power-down modes for high-impedance or pull-down states.

Applications

• Set point or offset trimming
• Sensor calibration
• Motor control systems

Procurement Notes

Verify the specific ordering suffix 'T' indicates reel packaging when sourcing components. Confirm that the '-E' suffix corresponds to the extended temperature grade required for the application environment. Ensure compatibility with the 20-QFN footprint during PCB layout review.

Selection Notes

Select this component when four independent 12-bit channels are required alongside persistent memory for power-up state retention. Consider the 20-QFN package constraints and thermal pad requirements for heat dissipation. Evaluate the SPI clock speed limits against the system's processing capabilities to ensure reliable data transfer.

Part Context

This part belongs to the MCP48CXBX4/8 family of digital-to-analog converters. It shares architectural similarities with volatile memory variants like the MCP48CVB24 but distinguishes itself through integrated nonvolatile storage. The device complements other Microchip data converter solutions by offering multi-channel precision with programmable hardware persistence.
