MCP47FVB22A0-E/ST

Digital To Analog Converters Overview

The MCP47FVB22A0-E/ST is a dual-channel, 12-bit volatile digital-to-analog converter (DAC) manufactured by Microchip Technology. It features an I²C serial interface and operates within a supply voltage range of 2.7V to 5.5V for full specifications, or 1.8V to 2.7V with reduced analog performance. The device provides rail-to-rail buffered voltage outputs with a typical settling time of 6 µs. It supports Standard (100 kHz), Fast (400 kHz), and High-Speed (up to 3.4 MHz) communication modes. Power consumption is low, drawing less than 380 µA during normal operation and approximately 650 nA in power-down mode. The component is housed in an 8-lead TSSOP package and functions reliably across an extended temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Dual-channel architecture providing independent 12-bit resolution for two separate voltage outputs.
• Configurable reference sources including external VREF pin, internal band gap, or device VDD.
• Integrated output buffer with selectable unity or 2x gain settings when using the external reference.
• Supports high-voltage command functionality 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 'A0' against official documentation to confirm the exact factory default slave address and any unique manufacturing lot codes. Ensure the E/ST designation matches the required TSSOP-8 package and industrial temperature grade. Cross-reference the datasheet revision to confirm compatibility with your system's I2C timing requirements.

Digital To Analog Converters Selection Notes

Select this model when a dual-channel solution is required without non-volatile memory storage needs. The volatile RAM design necessitates re-initialization after power cycles. Consider the MCP47FEB22 series if data retention during power loss is critical. Verify that the 12-bit resolution meets the precision requirements of the target application.

Digital To Analog Converters Part Context

This component belongs to the MCP47FVBXX family of single and dual-channel DACs. It shares core architectural similarities with other members like the MCP47FVB12 but offers higher 12-bit resolution compared to the 8-bit or 10-bit variants. The 'A0' suffix typically denotes a specific factory-set I2C slave address configuration distinct from other addresses in the same package type.

Digital To Analog Converters Replacement Considerations

The MCP47FVB22T-E/UN serves as a functional equivalent in a different MSOP-10 package. For applications requiring non-volatile storage instead of volatile RAM, the MCP47FEB22 series is the direct alternative within the same family.
