Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance against the manufacturer's official documentation. Confirm that the '/250' designation corresponds to the required reel quantity of 250 units for your assembly process. Ensure the TQFP-32 package dimensions match your PCB footprint requirements before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high dynamic range and low noise are critical for small signal acquisition. The dual-channel design simplifies board layout for differential or paired sensor applications. Verify that the system power supply stability meets the 4.75 V to 5.25 V requirement to maintain specified accuracy levels.

Analog To Digital Converters (ADC) Part Context

This part belongs to the DDC112 family of precision ADCs designed specifically for medical imaging detectors. It serves as a direct replacement for earlier versions like the DDC112Y/2K, offering identical electrical performance in a RoHS-compliant package. The family is optimized for integrating directly with photodiode-based sensors.

Analog To Digital Converters (ADC) Replacement Considerations

The DDC112Y/2K is a confirmed functional substitute with identical pinout and specifications. The DDC112U variant offers the same performance in a SOIC-28 package, requiring adapter consideration.
