MCP48CMD21T-E/UN

Digital To Analog Converters Overview

The MCP48CMD21T-E/UN 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 within a supply voltage range of 2.7V to 5.5V for full specifications, with reduced analog specifications available between 1.8V and 2.7V. The device provides buffered voltage outputs with integral nonlinearity (INL) specified at ±1 LSB. Key electrical parameters include a typical settling time of 4 µs, a maximum write speed of 50 MHz, and a read speed of 25 MHz. It supports gain options of 1x or 2x and includes power-on/brown-out reset protection.

Digital To Analog Converters Feature Summary

• Integrates MTP nonvolatile memory allowing up to 32 user-programmable locations for persistent configuration and data storage.
• Offers flexible reference voltage sources including VDD, external VREF pin, and an internal band gap voltage.
• Supports high-speed SPI communication with configurable modes and simultaneous latch capabilities.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure compatibility with system voltage levels and temperature ranges before integration. Cross-reference the datasheet revision date to confirm current feature sets and electrical characteristics.

Digital To Analog Converters Selection Notes

Select this component when nonvolatile output retention is required without external EEPROMs. The 12-bit resolution suits applications needing moderate precision. Verify that the system can provide the necessary high-voltage level on the LAT/HVC pin if MTP programming is utilized during operation.

Digital To Analog Converters Part Context

This part belongs to the MCP48CXDX1/2 family of digital-to-analog converters. The 'CMD' designation indicates the inclusion of MTP nonvolatile memory, distinguishing it from volatile variants. The '21' suffix specifies a single-channel configuration with 12-bit resolution, while 'E' denotes the extended industrial temperature range.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include MCP48CMD21-E/UN (tube packaging) or MCP48CMD21-E/MF (DFN package). For volatile memory requirements, consider the MCP48CVD21 series. Dual-channel equivalents are available in the MCP48CMD22 series.
