MCP47FEB04-E/MQ

Digital To Analog Converters Overview

The MCP47FEB04-E/MQ is a quad-channel, 8-bit Digital-to-Analog Converter (DAC) featuring nonvolatile EEPROM memory and an I2C-compatible serial interface. It operates within a supply voltage range of 2.7V to 5.5V for full specifications, with reduced specifications available from 1.8V to 2.7V. The device provides rail-to-rail buffered voltage 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. The component utilizes a 20-lead VQFN package measuring 5 x 5 mm and is rated for an extended operating temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Nonvolatile EEPROM storage retains DAC register settings and configuration bits across power cycles.
• WiperLock™ functionality prevents inadvertent changes to stored output values using high-voltage commands.
• Configurable power-down modes allow selection between high-impedance output or internal pull-down resistors.

Digital To Analog Converters Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation
• PC peripherals
• 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 nonvolatile EEPROM variant matches system requirements for data retention during power loss. Ensure the I2C slave address configuration aligns with the host controller's bus topology. Check for any recent Product Change Notifications regarding manufacturing updates.

Digital To Analog Converters Selection Notes

Select this model when four independent analog channels are required in a compact footprint. The EEPROM feature is essential for applications needing persistent output states after power interruption. Verify that the 8-bit resolution meets the precision requirements of the target application. Consider the 20-lead VQFN package constraints for thermal management and PCB layout space.

Digital To Analog Converters Part Context

This component belongs to the MCP47FXBX4/8 family of buffered voltage output DACs. It shares the same analog circuit structure as volatile RAM versions but includes nonvolatile memory. The 'E' suffix indicates the extended industrial temperature range, while '/MQ' denotes the 20-lead VQFN package. Other family members include octal configurations and different resolution options.

Digital To Analog Converters FAQ

How does the WiperLock™ technology function?

It uses a high voltage on the LAT/HVC pin combined with dedicated commands to lock the values stored in memory, preventing inadvertent changes to the output value.

What are the available voltage reference sources?

The device supports three voltage reference sources: the external VREF pin, the device's VDD supply, or an internal band gap voltage source.

What is the maximum data transfer 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).
