MCP48FEB28T-E/MQ

Digital To Analog Converters Overview

The MCP48FEB28T-E/MQ is a quad-channel, 12-bit voltage output Digital-to-Analog Converter (DAC) from Microchip Technology. It features nonvolatile EEPROM memory for DAC codes and configuration bits, supporting auto-recall on power-up. The device operates with an analog supply voltage range of 2.7V to 5.5V and utilizes a 4-wire SPI interface with write speeds up to 20 MHz. Key electrical specifications include a typical settling time of 7.8 µs, rail-to-rail buffered outputs, and INL/DNL errors of ±0.4 LSB and ±0.05 LSB respectively. It is housed in a 20-VQFN package and qualified under AEC-Q100 standards.

Digital To Analog Converters Feature Summary

• Nonvolatile EEPROM storage enables automatic recall of DAC register settings and device configuration upon power restoration.
• Integrated WiperLock™ technology prevents inadvertent changes to stored output values using high-voltage commands.
• Flexible reference input options allow selection between external VREF pins, internal band gap, or device VDD.
• Dual latch inputs facilitate simultaneous updates across multiple channels via the LAT pin.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration requiring persistent data retention
• Low-power portable instrumentation
• Motor control applications

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing components. Confirm that the '-E' designation corresponds to the extended temperature range of -40°C to +125°C. Ensure the ordering part number matches the exact channel count and resolution requirements for the target design.

Digital To Analog Converters Selection Notes

Select this component for designs requiring four independent 12-bit outputs with nonvolatile memory capabilities. Consider the 20-VQFN package dimensions for PCB layout constraints. Evaluate the SPI interface speed requirements against the 20 MHz write limit. Verify compatibility with the available voltage reference sources for the desired output range.

Digital To Analog Converters Part Context

This part belongs to the MCP48FXBX4/8 family of digital-to-analog converters. It shares architectural similarities with volatile RAM-based variants like the MCP48FVB28 but distinguishes itself through integrated EEPROM for data persistence. The family supports both quad and octal channel configurations across various resolutions.
