MCP48CVB28-E/ML

Digital To Analog Converters Overview

The MCP48CVB28-E/ML is an octal-channel, 12-bit Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features volatile memory and a buffered voltage output architecture. The device 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. It utilizes a four-wire SPI serial interface supporting write speeds up to 50 MHz and read speeds up to 25 MHz. The component is housed in a 20-lead QFN package measuring 4 mm x 4 mm and is rated for extended industrial temperature operation from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Octal configuration providing eight independent buffered voltage outputs within a compact footprint.
• SPI-compatible serial interface enabling high-speed digital communication with standard microcontrollers.
• Flexible reference input options allowing selection between device VDD, external VREF, or internal bandgap sources.
• Integrated power-on and brown-out reset protection to ensure stable initialization.

Digital To Analog Converters Applications

• Set point or offset trimming in precision instrumentation
• Sensor calibration systems requiring multi-channel adjustment
• Low-power portable instrumentation devices
• Data acquisition systems with multiple analog channels
• Motor control applications

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Ensure that the volatile memory characteristic aligns with system requirements, as data is lost upon power removal. Confirm that the SPI interface timing parameters meet the host controller's maximum clock speed capabilities before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when eight simultaneous analog outputs are required without the need for non-volatile storage. Compare against the MCP48CMB28 variant if persistent settings across power cycles are necessary. Evaluate the 12-bit resolution against application accuracy needs and consider the 20-lead QFN package constraints for PCB layout and thermal management during the design phase.

Digital To Analog Converters Part Context

This part belongs to the MCP48CXBX4/8 family of 8-bit, 10-bit, and 12-bit DACs. The 'CV' designation indicates volatile RAM memory, distinguishing it from the 'CM' series which includes Multi-Time Programmable (MTP) non-volatile memory. The 'B28' suffix specifies the octal channel count and 12-bit resolution, while '/ML' denotes the 20-lead QFN package option.

Digital To Analog Converters Replacement Considerations

The MCP48CMB28-E/ML serves as a direct functional substitute within the same package, offering identical electrical performance but with added non-volatile MTP memory capabilities. Designers must account for the memory difference when selecting this alternative to ensure system behavior remains consistent.
