MCP48FEB24T-E/MQ

Digital To Analog Converters Overview

The MCP48FEB24T-E/MQ is a quad-channel, 12-bit Digital-to-Analog Converter (DAC) from the MCP48FXBX4/8 family. It features buffered voltage outputs with rail-to-rail capability and an SPI-compatible serial interface supporting up to 20 MHz writes. The device includes nonvolatile EEPROM memory for auto-recall of DAC register settings and configuration bits upon power-up or brown-out reset. Operating supply voltage ranges from 2.7V to 5.5V for full specifications, with reduced specifications available between 1.8V and 2.7V. It offers selectable voltage reference sources including VDD, external VREF, or an internal band gap, along with gain options of 1x or 2x.

Digital To Analog Converters Feature Summary

• Quad-channel 12-bit resolution with buffered rail-to-rail voltage outputs
• Nonvolatile EEPROM memory enabling automatic recall of DAC values and configuration settings after power cycles
• SPI interface compatible with Mode 0,0 and Mode 1,1, supporting high-speed data transfer
• WiperLock™ functionality to prevent inadvertent changes to stored output values

Digital To Analog Converters Applications

• Set point or offset trimming in industrial systems
• Sensor calibration requiring persistent configuration storage
• Low-power portable instrumentation
• Data acquisition systems
• Motor control applications

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'MQ' against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with system requirements for extended temperature range (-40°C to +125°C) and supply voltage levels. Confirm that the nonvolatile EEPROM feature aligns with application needs for power-on state retention.

Digital To Analog Converters Selection Notes

Select this component when a quad-channel DAC with nonvolatile memory is required. The 12-bit resolution provides 4096 steps for precise analog control. Consider the internal band gap reference if an external precision reference is not available. Verify that the SPI interface timing meets the master controller's capabilities, particularly regarding the 20 MHz write speed requirement.

Digital To Analog Converters Part Context

This part belongs to the MCP48FXBX4/8 family, which encompasses both volatile (RAM) and nonvolatile (EEPROM) versions in quad and octal configurations. The 'E' indicates extended temperature range operation, while 'MQ' typically denotes a specific package variant within the 20-lead TSSOP or VQFN options provided by the manufacturer for this family.
