MCP48CMD21T-E/MG

Digital To Analog Converters Overview

The MCP48CMD21T-E/MG is a single-channel, 12-bit Digital-to-Analog Converter (DAC) featuring Multi-Time Programmable (MTP) nonvolatile memory and an SPI serial interface. It operates on a single supply voltage ranging from 2.7V to 5.5V, with reduced specifications available for the 1.8V to 2.7V range. The device provides buffered voltage outputs with selectable unity or 2x gain. Key electrical parameters include a typical settling time of 4 µs, a maximum SPI write speed of 50 MHz, and an operating temperature range of -40°C to +125°C. It utilizes a resistor ladder architecture ensuring low differential nonlinearity.

Digital To Analog Converters Feature Summary

• Integrated MTP nonvolatile memory allows user-programmable storage of DAC codes and configuration registers for power-up retention.
• Flexible reference input options support device VDD, external VREF pin, or internal band gap voltage sources.
• SPI-compatible serial interface supports high-speed data transfer with simultaneous latching capabilities via the LAT/HVC pin.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring precise analog output
• Low-power portable instrumentation devices

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'MG' against the manufacturer's official documentation to confirm the package type and tape-and-reel quantity. Ensure the component meets the required extended temperature range specifications (-40°C to +125°C) for your application environment. Cross-reference the datasheet revision to confirm compatibility with your design requirements.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit resolution is required alongside nonvolatile memory retention without external EEPROM. Consider the 2x gain option if utilizing an external reference voltage below VDD/2. Verify that the system logic levels are compatible with the SPI interface thresholds across the specified supply voltage range.

Digital To Analog Converters Part Context

This part belongs to the MCP48CXDX1/2 family of 8-bit, 10-bit, and 12-bit DACs. The 'C' indicates MTP memory, 'D' denotes the dual/single channel variant (here single), 'M' specifies the 12-bit resolution, and '21' identifies it as a single-channel device. The 'T' indicates tape and reel packaging, while 'E' signifies the extended temperature grade.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include other MCP48CMDxx variants with different resolutions or volatile/nonvolatile memory configurations. For single-channel 12-bit DACs with similar interfaces, consider the MCP4921 series, though it lacks integrated nonvolatile memory.
