MCP48CVD21T-E/UN

Digital To Analog Converters Overview

The MCP48CVD21T-E/UN is a single-channel, 12-bit Digital-to-Analog Converter (DAC) featuring volatile memory and an SPI serial interface. It provides buffered voltage outputs with integral nonlinearity (INL) of ±1 LSB. The device operates on a supply voltage ranging from 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. Key electrical parameters include a settling time of 4 µs, a typical supply current of 190 µA at 1 MHz, and a maximum SPI write speed of 50 MHz. It supports gain options of 1x or 2x and utilizes external, VDD, or internal band gap reference sources.

Digital To Analog Converters Feature Summary

• Single-channel buffered voltage output with 12-bit resolution
• SPI-compatible serial interface supporting up to 50 MHz write speeds
• Configurable power-down modes with selectable pull-down resistors
• Extended temperature range operation from -40°C to +125°C

Digital To Analog Converters Applications

• Set point or offset trimming in industrial systems
• Sensor calibration circuits
• Low-power portable instrumentation
• PC peripherals requiring digital-to-analog conversion
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging rather than tube. Confirm that the 'E' suffix denotes the extended temperature grade (-40°C to +125°C). Ensure the 'V' designation corresponds to the volatile memory variant, distinguishing it from nonvolatile MTP versions. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility and electrical characteristics before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a single-channel DAC with volatile storage is required. The 12-bit resolution offers 4096 steps suitable for moderate precision applications. Consider the SPI interface speed requirements; write operations support up to 50 MHz. Evaluate power constraints against the 190 µA active current draw. If nonvolatile retention is necessary, choose the MCP48CMDX1 variant instead. Ensure the system voltage aligns with the 2.7V-5.5V full-specification range for optimal linearity.

Digital To Analog Converters Part Context

This part belongs to the MCP48CXDX1 family of 8-, 10-, and 12-bit DACs. The 'V' in the model number specifies volatile RAM-based data storage, meaning output values are lost upon power cycle unless reprogrammed. It contrasts with the 'M' suffix devices which feature Multi-Time Programmable (MTP) memory. The 'T' suffix typically denotes reel packaging for automated assembly, while 'UN' refers to the MSOP-10 package type.

Digital To Analog Converters Replacement Considerations

Public confirmed substitute part numbers: MCP48CVD21-E/UN (tube version), MCP48CVD11T-E/UN (10-bit version), MCP48CVD01T-E/UN (8-bit version). For nonvolatile requirements, consider MCP48CMD21T-E/UN.
