Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix (-820) matches the required 820 MSPS sampling rate during procurement. Confirm that the LFCSP-64 package orientation and pinout align with the target PCB footprint. Ensure the ordering information corresponds to the exact Analog Devices part number to avoid compatibility issues with system clocking and power requirements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel ADC with 14-bit resolution and up to 820 MSPS throughput is required. Consider the integrated DDC capabilities if digital signal processing within the receiver chain is desired. Evaluate the 2 GHz analog input bandwidth against the highest frequency components of the input signal to ensure adequate performance without aliasing or distortion.

Analog To Digital Converters (ADC) Part Context

This component belongs to the AD9680 family of dual-channel, 14-bit ADCs offered by Analog Devices. The family includes variants optimized for different sampling rates, such as 500 MSPS, 1 GSPS, and 1.25 GSPS. All variants share the same functional architecture and pinout, differing primarily in their specified maximum sampling frequencies and associated AC performance characteristics.
