Digital To Analog Converters Procurement Notes

Verify the obsolete status of this part number through official Analog Devices channels before procurement planning. Confirm availability from authorized distributors or surplus suppliers if standard production lines are discontinued. Ensure that the specific 20-SOIC package variant matches your board design requirements and that no newer replacement series is recommended for long-term manufacturing viability.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution with multiplying functionality is required. Consider the 1µs settling time for speed-sensitive designs. Evaluate the current-output nature against system load requirements. Verify compatibility with available supply voltages and ensure the 20-lead SOIC footprint fits the PCB layout constraints effectively.

Digital To Analog Converters Part Context

The PM7645BR belongs to the PM7645 family of CMOS D/A converters. It is distinct from other Analog Devices ADC models like the AD7915. The device represents a legacy product line focused on buffered multiplying conversions, differing from modern sigma-delta architectures.

Digital To Analog Converters Replacement Considerations

The manufacturer lists this product as obsolete. Check for direct pin-compatible replacements within the same family or updated series offering similar 12-bit multiplying specifications.
