Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRGCT indicates the reel packaging quantity of 250 units per reel, distinct from the IRGCR variant which contains 2000 units. Confirm RoHS compliance status through the manufacturer's official documentation prior to ordering. Ensure the procurement channel provides valid traceability for export control requirements if applicable to the destination region.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit resolution is sufficient for the application, offering lower power consumption compared to the 16-bit ADS42JB69 variant. Consider the ADS42LB69 if LVDS parallel output is preferred over the JESD204B serial interface. Evaluate the ADS42JB46 if a lower sampling rate of 160 MSPS meets system timing constraints while reducing power usage.

Analog To Digital Converters (ADC) Part Context
