MCP47CMB28-E/ML

Digital To Analog Converters Overview

The MCP47CMB28-E/ML is an octal-channel, 12-bit Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features Multi-Time Programmable (MTP) nonvolatile memory and operates via an I2C serial interface. The device supports a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. It utilizes a QFN-20 package and includes buffered voltage outputs.

Digital To Analog Converters Feature Summary

• Octal channel configuration providing eight independent buffered voltage outputs
• Nonvolatile MTP memory retains power-up output values and configuration data
• I2C compatible serial interface supporting Standard, Fast, and High-Speed modes

Digital To Analog Converters Applications

• Sensor calibration systems requiring multi-channel precision
• Set point or offset trimming in industrial instrumentation
• Low-power portable data acquisition devices

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the design accommodates the required I2C address configuration and MTP programming voltage levels if nonvolatile storage updates are necessary during operation.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated DAC channels are required within a single footprint. The 12-bit resolution offers high precision, while the MTP memory eliminates the need for external EEPROMs to store calibration constants. Verify that the system voltage aligns with the 2.7V–5.5V operating range for optimal linearity specifications.

Digital To Analog Converters Part Context

This part belongs to the MCP47CXBXX family of digital-to-analog converters. The 'MB' designation indicates the inclusion of nonvolatile MTP memory, distinguishing it from volatile RAM-based variants. The '28' suffix specifies the octal channel count and 12-bit resolution combination within the product line.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include other MCP47CMBxx variants with different channel counts or resolutions, such as MCP47CMB24 or MCP47CMB21, provided pin compatibility and memory requirements match.
