Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix BCPZ corresponds to the LFCSP-64 package and industrial temperature grade when sourcing. Confirm that the -80 designation indicates the 80 MSPS maximum sampling rate variant. Ensure compatibility with the AD9637-80EBZ evaluation board if initial prototyping is required. Check for RoHS compliance documentation as specified in the manufacturer's ordering guide.

Analog To Digital Converters (ADC) Selection Notes

Select this component for designs requiring high channel density and low power dissipation. The 1.8 V single-supply operation simplifies power management compared to dual-supply alternatives. Consider the serial LVDS interface requirements for PCB trace impedance matching. Evaluate thermal performance using the provided junction-to-ambient resistance values for the LFCSP package under expected airflow conditions.
