MCP48CMD02-E/MF

Overview

The MCP48CMD02-E/MF is a dual-channel, 8-bit Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory. It operates with an SPI serial interface and provides buffered voltage outputs. The device supports supply voltages from 1.8V to 5.5V, with full specifications guaranteed between 2.7V and 5.5V. Key electrical parameters include a typical settling time of 4 µs, a maximum Integral Nonlinearity (INL) of ±1 LSB, and a gain error of ±0.6% of Full Scale Range (FSR). It includes power-on/brown-out reset protection and configurable power-down modes.

Feature Summary

• Integrates MTP nonvolatile memory for retaining DAC output values and configuration settings across power cycles.
• Features a high-speed SPI interface supporting write speeds up to 50 MHz and read speeds up to 25 MHz.
• Offers flexible reference voltage options including VDD, external VREF, or an internal band gap source.
• Provides selectable output gain of 1x or 2x and configurable power-down states for low-power operation.

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature range. Ensure the design accounts for the high-voltage programming requirements on the LAT/HVC pin if utilizing the MTP memory features. Confirm compatibility with system voltage levels for the SPI interface signals.

Selection Notes

Select this component when dual-channel 8-bit resolution with persistent memory storage is required. Consider the 1.8V to 5.5V operating range for low-voltage applications. Evaluate the need for the internal band gap reference versus an external precision reference based on accuracy requirements. Verify that the MSOP-10 package fits the PCB layout constraints.

Part Context

This part belongs to the MCP48CXDX family of single and dual channel DACs. The 'C' indicates SPI interface, 'M' denotes MTP memory, 'D' signifies dual channels, and '02' specifies 8-bit resolution. The '-E' suffix typically indicates the extended industrial temperature range (-40°C to +125°C), while '/MF' identifies the specific MSOP-10 package variant.

Replacement Considerations

Direct replacements within the same family include other MCP48CMD02 variants with different packages (e.g., QFN or DFN) or resolutions (MCP48CMD12 for 10-bit, MCP48CMD22 for 12-bit). Volatile memory versions like MCP48CVD02 are functionally similar but lack nonvolatile storage.
