MCP47FEB12A1-E/ST

Digital To Analog Converters Overview

The MCP47FEB12A1-E/ST is a dual-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) with nonvolatile EEPROM memory and an I²C serial interface. It operates on a supply voltage of 1.8V to 5.5V, supporting full specifications from 2.7V to 5.5V and reduced specifications from 1.8V to 2.7V. The device features rail-to-rail outputs, a typical settling time of 6 µs, and selectable reference sources including VDD, external VREF, or an internal bandgap. It supports Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) I²C modes within an extended temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture with integrated nonvolatile EEPROM for persistent DAC settings and configuration recall.
• I²C-compatible serial interface supporting Standard, Fast, and High-Speed communication modes.
• Flexible voltage reference selection with configurable unity or two-times gain options for the output buffer.

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 'A1' against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Ensure the ordering code matches the required package type and temperature grade before procurement. Cross-reference the datasheet revision date to validate parameter accuracy.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with nonvolatile storage is required. The 12-bit resolution provides high precision for analog control applications. Verify that the system power supply falls within the 1.8V to 5.5V range and that the I²C bus speed requirements are met by 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 '12' designation indicates 12-bit resolution, while 'X2' denotes the dual-channel configuration. The 'E' suffix typically signifies the extended industrial temperature range, and '/ST' identifies the TSSOP-8 package option.

Digital To Analog Converters Replacement Considerations

Check for other members of the MCP47FEBXX series, such as MCP47FEB11A1-E/ST for single-channel or MCP47FEB22A1-E/ST for 12-bit variants. Ensure any substitute maintains the same I²C addressability and EEPROM functionality if nonvolatile retention is critical.
