MCP47FEB21A3T-E/ST

Digital To Analog Converters Overview

The MCP47FEB21A3T-E/ST is a single-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 1.8V to 5.5V and supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) communication modes. The device provides rail-to-rail output with a typical settling time of 6 µs. It includes power-on/brown-out reset protection, multiple power-down modes, and a user-programmable high-voltage latch input.

Digital To Analog Converters Feature Summary

• Integrated nonvolatile EEPROM for automatic recall of DAC settings, reference configuration, and gain upon power-up or brown-out events.
• Configurable voltage reference sources including external VREF pin, internal band gap, or device VDD, with selectable unity or 2x output buffer gain.
• High-speed I²C compatibility supporting up to 3.4 Mbps operation alongside standard and fast mode protocols.
• Dedicated high-voltage command input allowing direct control of the output state without serial interface interaction.

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 suffix 'A3' against the manufacturer's official documentation to confirm the exact slave address assignment and any unique factory programming configurations. Ensure the ordering information matches the required package type and temperature grade specifications before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit resolution is required with persistent output states across power cycles. Consider the available reference options and the necessity for high-speed I²C communication. Verify that the operating voltage range aligns with the system's power supply constraints and that the TSSOP-8 package fits the board layout requirements.

Digital To Analog Converters Part Context

This part belongs to the MCP47FEBXX family of nonvolatile DACs from Microchip Technology. It shares core architectural features with other members like the MCP47FEB0X and MCP47FEB1X, differing primarily in its 12-bit resolution which offers 4096 distinct output steps compared to lower-resolution variants.

Digital To Analog Converters Replacement Considerations

Direct replacements within the same family include MCP47FEB21A1T-E/ST or MCP47FEB21A2T-E/ST, provided the specific slave address configuration associated with the 'A3' suffix meets the system design requirements.
