MCP47FVB12A0T-E/STVAO

Digital To Analog Converters Overview

The MCP47FVB12A0T-E/STVAO 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 device specifications. 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) modes. Power consumption is less than 180 µA in normal operation and approximately 650 nA in power-down mode.

Digital To Analog Converters Feature Summary

• Configurable voltage reference sources including VDD, external VREF pin, or internal band gap.
• Integrated power-on and brown-out reset protection mechanisms.
• Supports high-voltage commands compatible with MCP47FEBXX devices.

Digital To Analog Converters Applications

• Set point or offset trimming
• Sensor calibration
• Low-power portable instrumentation
• Data acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'VAO' against the manufacturer's official documentation to confirm environmental compliance status and any potential changes in package material or lead finish. Ensure the ordering information matches the exact part number required for your bill of materials to avoid discrepancies in component specifications.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel solution with 12-bit precision is required. Note that the device utilizes volatile RAM; system designs must account for data retention during power cycles. Verify that the application environment stays within the specified temperature range of -40°C to +125°C for optimal performance.

Digital To Analog Converters Part Context

This part belongs to the MCP47FVBXX family of single and dual-channel DACs. It shares architectural similarities with the non-volatile MCP47FEBXX series but differs in its use of volatile memory instead of EEPROM. The device is designed for applications requiring fast updates and low power consumption via the I²C interface.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same family include the MCP47FVB02A0T-E/STVAO (8-bit) and MCP47FVB12A0T-E/STVAO (10-bit). Cross-family replacements like the MCP4728 series offer non-volatile storage but may differ in interface compatibility and pinout configuration.

Digital To Analog Converters FAQ

What happens to the DAC output values after a power cycle?

Because the MCP47FVB12A0T-E/STVAO uses volatile RAM, the DAC register values are lost upon power loss. The device resets to its factory default POR/BOR setting upon power-up.

Can the device operate with a digital voltage lower than the analog supply?

Yes, the LAT/HVC pin has Schmitt trigger inputs that allow for 2.7V digital logic levels even when the analog VDD is higher, supporting mixed-voltage systems.

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 to ensure proper operation.
