Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CKZXGR' against official Texas Instruments documentation to confirm package variant and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 64-NFBGA form factor. Confirm that the required external components, such as capacitors and references, meet the electrical characteristics defined in the datasheet for stable operation at the target operating frequency.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems requiring a high number of current-input channels with 20-bit precision. It is appropriate for applications where space constraints favor a dense NFBGA package over discrete solutions. Consider the SPI interface requirements and the need for an external reference voltage source when evaluating system complexity. Compare channel count and resolution against alternatives like the DDC118 or DDC264 if the application demands different scaling factors.
