MCP48CMB04T-E/ML

Overview

The MCP48CMB04T-E/ML is a quad-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory and an SPI serial interface. It operates on a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. The device provides four independent DAC outputs with a settling time of 4µs and supports SPI write speeds up to 50 MHz. It includes power-on/brown-out reset protection and configurable power-down modes.

Feature Summary

• Integrates MTP nonvolatile memory allowing user programming up to 32 times per register for persistent configuration storage.
• Offers flexible voltage reference selection from device VDD, external VREF pin, or internal band gap source.
• Supports dual gain options of 1x and 2x when utilizing external reference voltages.
• Includes programmable power-down modes that disconnect the output buffer or select specific pull-down resistor values.

Applications

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

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure the design accommodates the high-voltage requirement on the HVC pin for MTP programming operations. Confirm that the system logic levels are compatible with the specified SPI interface thresholds across the operating voltage range.

Selection Notes

Select this component when quad-channel resolution with nonvolatile data retention is required. Compare against volatile variants if power loss persistence is unnecessary. Verify that the 8-bit resolution meets the application's accuracy requirements and that the SPI interface speed aligns with the host controller's capabilities.

Part Context

This part belongs to the MCP48CXBX4 family of quad-channel DACs. It shares the same physical footprint and pinout as other members like the MCP48CVB04T-E/ML but differs by incorporating MTP memory instead of volatile RAM. This allows it to retain DAC output values and configuration settings after power cycles without external backup batteries.

Replacement Considerations

The MCP48CVB04T-E/ML serves as a direct functional substitute if nonvolatile memory is not required. Other family members such as the MCP48CMB14T-E/ML offer higher resolution but may require software adjustments due to different bit depths.
