MCP47FEB21A2-E/ST

Digital To Analog Converters Overview

The MCP47FEB21A2-E/ST is a single-channel, 12-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 supply voltages ranging from 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 180 µA in normal operation. It utilizes VDD, external VREF, or an internal 1.22V bandgap reference.

Digital To Analog Converters Feature Summary

• Integrated nonvolatile EEPROM memory enables automatic recall of DAC register settings, device configuration, and Power-on Reset (POR)/Brown-out Reset (BOR) output states upon power cycling.
• Configurable output buffer gain allows selection between unity (1x) and double (2x) amplification when utilizing the external VREF pin as the voltage source.
• Flexible reference input options support connection to the device VDD, an external VREF pin, or the internal bandgap voltage generator.
• Includes power-down modes that disconnect the output buffer or select specific pull-down resistor values to minimize current consumption.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure the I²C slave address configuration matches the system requirements, as this model supports user-programmable addresses. Confirm that the selected operating voltage falls within the specified range for the desired performance specifications.

Digital To Analog Converters Selection Notes

Select this component when a single-channel DAC with persistent state retention is required. The 12-bit resolution provides 4096 distinct output steps. Consider the available reference sources and whether the internal bandgap or external VREF better suits the application's accuracy needs. Verify that the I²C bus speed requirements are compatible with the device's supported modes.

Digital To Analog Converters Part Context

This part belongs to the MCP47FEBXX family of single- and dual-channel DACs. The '2' in the model number indicates 12-bit resolution, while '1' denotes a single channel. The 'E' suffix typically signifies an extended industrial temperature range. This series is designed for applications requiring small form factors and low power consumption with nonvolatile data storage capabilities.

Digital To Analog Converters Replacement Considerations

Check for other members of the MCP47FEBXX family with different resolutions or channel counts. Verify compatibility with alternative I²C-compatible DACs if pinout differences exist. Ensure any substitute maintains the required nonvolatile memory functionality and operating voltage range.
