MCP47FVB28T-20E/ST

Digital To Analog Converters Overview

The MCP47FVB28T-20E/ST is an octal-channel digital-to-analog converter manufactured by Microchip Technology. It features 8-bit resolution and utilizes volatile memory to store output data. The device communicates via a standard I2C interface, supporting multiple clock speeds for flexible system integration. It operates within a supply voltage range of 2.7V to 5.5V for both analog and digital domains. The component is housed in a 20-pin Thin Shrink Small Outline Package (TSSOP) with a width of 4.40mm, designed for surface-mount assembly.

Digital To Analog Converters Feature Summary

• Octal channel configuration providing eight independent voltage outputs
• I2C serial interface for simplified microcontroller connectivity
• Non-volatile EEPROM option available in the family for data retention

Digital To Analog Converters Applications

• Multi-channel sensor signal conditioning
• Programmable bias voltage generation
• Industrial process control systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the '20E' designation aligns with the required temperature grade and package variant. Ensure the I2C address configuration matches the target system design constraints before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this model for applications requiring eight simultaneous analog outputs from a single IC. Consider the volatile nature of the memory; if power-down state retention is critical, evaluate non-volatile variants within the same product family. Verify that the I2C bus speed requirements are compatible with the device specifications.

Digital To Analog Converters Part Context

This component belongs to the MCP47FVBxx series of multi-channel DACs. It shares architectural similarities with other members like the MCP47FVB08 and MCP47FVB24, differing primarily in channel count and resolution. The TSSOP-20 package allows for compact PCB layouts in space-constrained designs.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other octal DACs from Microchip such as the MCP47FVB08T-20E/ST if lower resolution is acceptable. Cross-compatibility with similar I2C DAC families requires verification of pinout and register mapping.
