MCP47FEB24T-E/MQ

Digital To Analog Converters Overview

The MCP47FEB24T-E/MQ is a quad-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) featuring nonvolatile EEPROM memory and an I²C serial interface. It operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. The device provides rail-to-rail outputs with a typical settling time of 7.8 µs. It supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) data transfer rates. Memory retention is rated at 200 years at +25°C, with an endurance of 1 million write cycles.

Digital To Analog Converters Feature Summary

• Nonvolatile EEPROM storage enables automatic recall of DAC register settings, voltage reference configurations, and power-down states upon power-on or brown-out reset events.
• WiperLock™ functionality utilizes high-voltage commands on dedicated pins to prevent inadvertent changes to stored output values.
• Flexible voltage reference architecture allows selection between the external VREF pin, internal band gap source, or device VDD, supporting gain adjustments in buffered modes.

Digital To Analog Converters Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and temperature grade. Confirm that the 'E' designation corresponds to the extended industrial temperature range (-40°C to +125°C). Ensure the 'MQ' suffix matches the required 20-lead VQFN 5x5 mm package configuration before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when multi-channel precision conversion with persistent state retention is required. The 12-bit resolution offers 4096 steps suitable for moderate accuracy applications. Consider the 20-lead VQFN package for space-constrained designs requiring thermal dissipation via the exposed pad. Verify I²C address compatibility if multiple devices share the bus.

Digital To Analog Converters Part Context

This part belongs to the MCP47FXBX4/8 family, which includes volatile RAM and nonvolatile EEPROM variants in both quad and octal channel configurations. The 'FEB' designation specifically identifies the 12-bit nonvolatile version. The 'T' indicates tape-and-reel packaging, while 'E' denotes the extended temperature rating.

Digital To Analog Converters Replacement Considerations

MCP47FEB24T-E/ML: Identical electrical specifications and functionality; differs only in package style (QFN-20 vs. VQFN-20).

Digital To Analog Converters FAQ

How does the WiperLock™ feature function?

WiperLock™ prevents accidental modification of stored DAC values by requiring a high-voltage signal on the LAT/HVC pin alongside specific I²C commands to unlock the memory for writing.

What are the available voltage reference sources?

The device supports three reference sources: the external VREF pin, the internal band gap voltage (typically 1.22V), or the device's own VDD supply.

What is the maximum data rate supported by the I²C interface?

The I²C interface supports Standard mode (100 kbps), Fast mode (400 kbps), and High-Speed mode (up to 3.4 Mbps).
