MCP48CVB21-E/MF

Digital To Analog Converters Overview

The MCP48CVB21-E/MF is a single-channel, 12-bit Digital-to-Analog Converter (DAC) from Microchip Technology. It features volatile memory and an SPI serial interface. The device operates with supply voltages ranging from 2.7V to 5.5V for full specifications, or 1.8V to 2.7V for reduced specifications. It offers buffered voltage output with reference source options including VDD, external VREF, or an internal bandgap. Key electrical parameters include a settling time of 16 µs, ±1 LSB Integral Nonlinearity (INL), and ±1 LSB Differential Nonlinearity (DNL). The component supports SPI modes '00' and '11' with write speeds up to 50 MHz and read speeds up to 25 MHz. It is housed in a DFN-10 package and functions within an extended temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrates volatile DAC registers for data storage without non-volatile retention capabilities.
• Provides buffered voltage output with selectable gain settings of 1x or 2x.
• Supports multiple voltage reference sources including device VDD, external VREF pin, and internal bandgap.
• Includes Power-on/Brown-out Reset (POR/BOR) protection mechanisms.

Digital To Analog Converters Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation
• PC peripherals
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels, as performance specifications vary between the 2.7V–5.5V and 1.8V–2.7V operating ranges. Confirm that the volatile memory architecture aligns with application requirements for power-up states.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, high-resolution digital-to-analog conversion is required with SPI connectivity. Consider the DFN-10 package for space-constrained designs. Evaluate the need for volatile versus non-volatile memory; if power-down state retention is necessary, alternative models within the MCP48CXBXX family featuring MTP memory should be considered.

Digital To Analog Converters Part Context

This part belongs to the MCP48CXBXX family of 8/10/12-bit Digital-to-Analog Converters. The family includes variants with different resolutions, channel counts, and memory types. The CVB designation specifically indicates a single-channel device with volatile memory, distinguishing it from CMB variants which feature Multi-Time Programmable (MTP) non-volatile memory.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include MCP48CVB21-E/UN (MSOP-10 package) or MCP48CVB21-E/ML (QFN-16 package). For non-volatile alternatives, consider MCP48CMB21-E/MF. Verify pinout compatibility and thermal characteristics when substituting packages.
