MCP48CVD22-E/UN

Digital To Analog Converters Overview

The MCP48CVD22-E/UN is a dual-channel, 12-bit volatile Digital-to-Analog Converter (DAC) from Microchip Technology. It features buffered voltage outputs and 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 utilizes a four-wire SPI-compatible serial interface supporting write speeds up to 50 MHz and read speeds up to 25 MHz. Key electrical characteristics include a typical settling time of 4 µs, an Integral Nonlinearity (INL) specification of ±1 LSB, and a typical gain error of ±0.1% of Full Scale Range (FSR). It incorporates Power-on/Brown-out Reset protection and offers selectable output gain options of 1x or 2x.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with independent configuration capabilities for each DAC output.
• High-precision performance characterized by a 1 LSB Integral Nonlinearity (INL) specification.
• Flexible reference source selection allowing operation with VDD, external VREF, or internal band gap voltage.
• Integrated WiperLock™ technology enabling simultaneous latch updates for synchronized channel control.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration requiring high accuracy
• Low-power portable instrumentation
• Data acquisition systems

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 nature of the CVD series is accounted for in system design, as power loss results in data retention loss. Confirm compatibility with the host microcontroller's SPI voltage levels and timing requirements before integration.

Digital To Analog Converters Selection Notes

Select this component when dual-channel synchronization and high linearity are required without the need for nonvolatile storage. Compare against the CMD series if power-up state preservation is necessary. Consider the MSOP-10 package constraints regarding thermal dissipation and pin pitch. Evaluate the 1.8V operating mode requirements if low-voltage applications are targeted, noting the associated reduction in analog specifications.

Digital To Analog Converters Part Context

This part belongs to the MCP48CXDX family of 8, 10, and 12-bit DACs. The 'V' designation specifically indicates volatile RAM-based memory, distinguishing it from the 'M' series which includes Multi-Time Programmable (MTP) nonvolatile memory. It shares the same core analog performance and SPI interface as other members of the CXD family but lacks the user-programmable MTP registers.

Digital To Analog Converters Replacement Considerations

The MCP48CMD22-E/UN serves as a direct functional replacement if nonvolatile memory retention is required, though it involves different programming procedures. Single-channel equivalents like the MCP48CVD21-E/UN may be used if only one output is needed. Verify pinout compatibility across MSOP-10 packages within the family.
