MCP47FEB01A3T-E/ST

Digital To Analog Converters Overview

The MCP47FEB01A3T-E/ST is a single-channel, 8-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 2.5V with reduced analog performance. The device provides rail-to-rail output with a typical settling time of 6 µs. Reference sources include the internal band gap (1.22V), external VREF pin, or device VDD. It supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) communication modes.

Digital To Analog Converters Feature Summary

• Integrated nonvolatile EEPROM memory retains DAC settings, configuration bits, and power-on reset states across power cycles.
• Configurable output buffer gain allows selection between unity (1x) and doubled (2x) amplification when using external reference inputs.
• Flexible power-down modes enable high-impedance output isolation or selectable pull-down resistor configurations for low-power applications.

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 current datasheet to confirm package type and tape-and-reel quantity. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the date code and lot traceability with authorized distributors to maintain supply chain integrity and avoid counterfeit parts.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 8-bit resolution is sufficient for the application. Consider the MCP47FEB1X series if higher 10-bit resolution is required, or the MCP47FEB2X series for 12-bit precision. Verify that the I2C bus speed requirements align with the device's support for standard, fast, and high-speed modes.

Digital To Analog Converters Part Context

This part belongs to the MCP47FEBXX family of nonvolatile DACs from Microchip Technology. The '01' designation indicates an 8-bit resolution variant with a single channel. The 'A3' suffix typically denotes a specific factory default slave address or configuration setting defined by the manufacturer.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include MCP47FEB01A1-E/ST and MCP47FEB01A2-E/ST, which share identical electrical characteristics but may differ in default slave addresses. For higher resolution needs, consider the MCP47FEB11A3T-E/ST (10-bit) or MCP47FEB21A3T-E/ST (12-bit).

Digital To Analog Converters FAQ

What are the available voltage reference options for the MCP47FEB01A3T-E/ST?

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

Does the MCP47FEB01A3T-E/ST retain its output value after a power cycle?

Yes, the device features nonvolatile EEPROM memory that automatically recalls the saved DAC register setting, voltage reference selection, gain, and power-down mode upon power-up or brown-out reset.

What is the maximum operating temperature for this component?

The MCP47FEB01A3T-E/ST is rated for an extended industrial temperature range, operating reliably from -40°C to +125°C.
