MCP47FEB02A0-E/ST

Digital To Analog Converters Overview

The MCP47FEB02A0-E/ST is a dual-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features nonvolatile EEPROM memory and an I²C serial interface supporting Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) modes. The device operates with a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V for reduced analog performance. Key electrical parameters include a typical settling time of 6 µs, rail-to-rail output capability, and low power consumption of less than 380 µA in normal operation. It utilizes a single VREF input and includes Power-on/Brown-out Reset protection.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with integrated nonvolatile EEPROM for persistent DAC register and configuration storage.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure the I²C bus speed requirements match the system controller capabilities. Confirm that the supply voltage levels align with the specified operating ranges for optimal performance.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with nonvolatile memory is required to reduce board space. Consider the 8-bit resolution limits for precision applications. Evaluate the I²C address conflicts if multiple devices are used on the same bus, as user-programmable addresses are available.

Digital To Analog Converters Part Context

This part belongs to the MCP47FEBXX family of digital-to-analog converters from Microchip Technology. The series offers various resolutions and channel counts, sharing common interface protocols and memory architectures. It is designed for applications requiring precise analog control with data retention capabilities across power cycles.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include other MCP47FEBxx variants with different resolutions or channel counts. Verify pin compatibility and software register mapping before substituting with single-channel or higher-resolution models.

Digital To Analog Converters FAQ

What is the default output state after a Power-on Reset?

The factory default POR/BOR setting for the MCP47FEB02 is 7Fh (full scale for 8-bit).

Can the I²C slave address be customized?

Yes, the device supports four predefined addresses or allows the user to program all seven bits of the slave address via nonvolatile memory.

How does the device handle power-down modes?

Power-down modes disconnect the output buffer into a high-impedance state or select pull-down resistors (100 kΩ or 1 kΩ) to minimize current consumption.
