Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix RL7 against the manufacturer's current documentation to confirm reel packaging specifications. Ensure compatibility with the required 32-lead LFCSP footprint and thermal pad soldering requirements. Confirm that the -80 speed grade meets the target sampling rate for the intended application design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit resolution and 80 MSPS sampling rate are required within a compact form factor. The AD9649 is pin-compatible with the AD9629 and AD9609, facilitating migration between different bit-depth converters. Consider the separate DRVDD supply for flexible digital interface voltage levels ranging from 1.8 V to 3.3 V.

Analog To Digital Converters (ADC) Part Context

The AD9649 belongs to the AD9649 series of 14-bit ADCs available in multiple speed grades (20, 40, 65, and 80 MSPS). It shares architectural similarities with other Analog Devices high-speed converters but is distinct in its specific combination of 14-bit resolution and pipeline topology. The part is designed to replace older generations of ADCs in space-constrained designs.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9649 is pin-compatible with the AD9629 (12-bit) and AD9609 (10-bit) for migration purposes. No direct public substitute part numbers are confirmed in the provided documentation.
