MCP47FVB12A1-E/ST

Digital To Analog Converters Overview

The MCP47FVB12A1-E/ST is a dual-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) with volatile 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 2.7V for reduced analog performance. The device features rail-to-rail outputs, a typical settling time of 6 µs, and supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I²C modes. Reference sources include the device VDD, an external VREF pin, or an internal band gap voltage.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing independent buffered voltage outputs controlled via a two-wire I²C-compatible serial interface.
• Configurable reference voltage selection allowing operation from the device supply, an external pin, or an internal band gap source.
• Integrated power management including power-on/brown-out reset protection and multiple low-power shutdown states.

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 package type and temperature grade. Ensure the design accounts for the volatile nature of the DAC registers, as data is lost upon power removal. Confirm that the I²C bus speed requirements align with the supported Standard, Fast, or High-Speed modes defined in the datasheet.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with 12-bit resolution is required. Consider the volatile memory characteristic if power loss data retention is necessary, as non-volatile EEPROM variants exist within the same family. Verify that the operating voltage range meets the system's power supply constraints and that the TSSOP-8 package fits the board layout.

Digital To Analog Converters Part Context

This part belongs to the MCP47FVBXX family of single and dual-channel DACs. It shares core architectural features with other members like the MCP47FVB12A1-E/ST but differs in channel count and resolution. The 'VB' designation indicates volatile RAM storage, distinguishing it from the 'EB' series which utilizes non-volatile EEPROM for data retention across power cycles.

Digital To Analog Converters Replacement Considerations

The MCP47FVB12A1-E/ST is functionally compatible with other devices in the MCP47FVBX2 series, such as the MCP47FVB02 or MCP47FVB22, provided the resolution requirements match. For non-volatile applications, the MCP47FEB12A1-E/ST serves as a direct substitute with identical electrical characteristics but includes EEPROM storage.
