Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BG4' against the manufacturer's official datasheet to confirm pinout compatibility and RoHS status. Ensure the ordering part number matches the exact package variant required for the PCB footprint. Cross-reference the revision level to avoid discrepancies in electrical characteristics or mechanical dimensions during procurement.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution is sufficient for the application's accuracy requirements. It is suitable for designs constrained by space due to the TSSOP package. Consider the parallel interface requirement; if serial communication is preferred, alternative models like the DAC7611 should be evaluated. Verify that the load impedance matches the output drive capabilities of the current source architecture.

Digital To Analog Converters Part Context

The DAC7621E belongs to the Burr-Brown family of precision digital-to-analog converters acquired by Texas Instruments. This series is designed for general-purpose applications requiring moderate resolution and speed. The 'G4' suffix typically indicates lead-free construction compliant with RoHS directives, distinguishing it from older non-compliant variants while maintaining identical functional specifications.

Digital To Analog Converters Replacement Considerations

Direct replacements include the DAC7621E and DAC7621EB. For pin-compatible alternatives with similar specifications, consider the DAC7611 for serial interfaces or the DAC7821 for multiplying applications. Always verify package dimensions and electrical parameters before substituting.
