YINGHUA AD6644ASTZ-65 ADC

The YINGHUA AD6644ASTZ-65 is a 65 MSPS analog-to-digital converter supplied in a 52-pin LQFP package. It is intended for engineers and system integrators who need high-speed signal acquisition in instrumentation, communications or data-acquisition designs. The device converts analogue inputs into digital data for downstream processing. It is not suited to applications requiring higher sample rates or different package pin counts.

Installing the LQFP-52 ADC

The 52-lead LQFP footprint requires standard surface-mount soldering with attention to pad alignment and thermal relief. Incorrect reflow profiles or insufficient decoupling near the supply pins typically cause conversion errors or device damage. Verify the pinout against the datasheet before layout to avoid mirrored or rotated placement. No through-hole adaptation is provided for this package.

Questions about this item

How can I verify the AD6644ASTZ-65 is operating correctly after soldering it onto the board?

Apply a known analogue input signal and capture the digital output; confirm the sample rate reaches 65 MSPS and the output codes match the expected transfer function for the 6644 architecture.

What ships with the AD6644ASTZ-65 and what must I source separately?

The reel or tray contains only the 52-pin LQFP IC; you must supply the PCB footprint, decoupling capacitors, reference-voltage circuitry, and any required clock driver.
