MCP48CMD02-E/MG

Overview

The MCP48CMD02-E/MG is a dual-channel, 8-bit Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory and an SPI serial interface. It operates within a supply voltage range of 2.7V to 5.5V for full specifications, with reduced analog specifications available between 1.8V and 2.7V. The device provides buffered voltage outputs with selectable gain options of 1x or 2x. Key electrical parameters include a maximum Integral Nonlinearity (INL) of ±1 LSB and a typical settling time of 4 µs. The SPI interface supports write speeds up to 50 MHz and read speeds up to 25 MHz. It includes power-on/brown-out reset protection and configurable power-down modes.

Feature Summary

• Integrated MTP nonvolatile memory allows user programming of output values and configuration registers without external storage components.
• Flexible reference voltage selection enables operation using the internal band gap, the VDD supply, or an external VREF pin.
• Dual latch architecture supports simultaneous updates of both DAC channels via the LAT pin.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current package availability list. Confirm that the MG suffix corresponds to the required MSOP-10 physical dimensions and thermal characteristics for your PCB layout. Ensure the component meets RoHS compliance standards for your target market regulations.

Selection Notes

Select this model when dual-channel output with nonvolatile retention is required. Choose the 8-bit resolution variant if lower precision suffices for cost reduction. Verify that the system voltage falls within the 2.7V to 5.5V range for optimal performance specifications.

Part Context

This component belongs to the MCP48CXDX family of digital-to-analog converters. It shares architectural similarities with volatile variants like the MCP48CVD02 but adds MTP memory capabilities found in the CMD series. The dual-channel configuration distinguishes it from single-channel models such as the MCP48CMD01.

Replacement Considerations

Direct functional replacements include other MCP48CMD02 variants with different package suffixes, such as MCP48CMD02-E/UN or MCP48CMD02-E/ML. Cross-referencing pin compatibility and thermal requirements is essential when substituting package types.
