MCP47FVB12A0T-E/ST

Digital To Analog Converters Overview

The MCP47FVB12A0T-E/ST is a dual-channel, 12-bit buffered voltage output Digital-to-Analog Converter (DAC) manufactured by Microchip Technology. It features volatile memory and an I²C serial interface supporting Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) modes. The device operates within a supply voltage range of 2.7V to 5.5V for full specifications, with reduced specifications available from 1.8V to 2.7V. Key electrical parameters include a typical settling time of 6 µs, rail-to-rail output capability, and low power consumption of less than 380 µA in normal operation. It includes power-on/brown-out reset protection and multiple power-down modes.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing two independent 12-bit DAC outputs within a single package.
• Configurable voltage reference sources including VDD, external VREF pin, or internal band gap.
• I²C compatibility with support for High Voltage Command (HVC) functionality.
• Integrated power management features such as configurable pull-down resistors and low-power shutdown states.

Digital To Analog Converters Applications

• Set point or offset trimming in industrial control systems
• Sensor calibration circuits requiring precise analog adjustments
• Low-power portable instrumentation devices
• Motor control applications needing variable voltage references

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature grade. Ensure that the selected variant matches the required I²C slave address configuration and memory volatility characteristics for the target design.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution is required without non-volatile storage, as the MCP47FVB series utilizes volatile RAM. Compare against the MCP47FEB series if data retention during power loss is necessary. Confirm that the 12-bit resolution and 6 µs settling time meet the system's accuracy and speed requirements.

Digital To Analog Converters Part Context

This part belongs to the MCP47FVBXX family of digital-to-analog converters. It is distinguished from the MCP47FEBXX series by its use of volatile RAM instead of EEPROM for data storage. The '12' in the model number indicates 12-bit resolution, while 'X2' denotes the dual-channel configuration.

Digital To Analog Converters FAQ

What is the difference between the MCP47FVB and MCP47FEB series?

The MCP47FVB series uses volatile RAM for DAC value storage, whereas the MCP47FEB series uses non-volatile EEPROM. This means values are lost upon power cycling in the FVB series unless retained externally.

Can the MCP47FVB12 support High-Speed I²C mode?

Yes, the device supports Standard (100 kbps), Fast (400 kbps), and High-Speed (up to 3.4 Mbps) I²C modes.

How does the gain setting affect the external reference voltage?

When using an external VREF pin, the user can select a gain of 1x or 2x. If the gain is set to 2x, the VREF pin voltage must be limited to a maximum of VDD/2.
