Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix '370' indicates the 370 MSPS speed grade variant during procurement. Confirm package type LFCSP-56 matches the target PCB footprint. Ensure the ordering documentation explicitly lists the Analog Devices manufacturer code to avoid counterfeit components. Check RoHS compliance status if required by local regulations.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high dynamic range is required at moderate high speeds. The 370 MSPS limit distinguishes it from the 500 MSPS variant. Consider the 1.8 V supply requirement for power budgeting. Evaluate thermal dissipation needs given the 660 mW power consumption. Verify FPGA compatibility with LVDS output standards.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9434 family, which also includes a 500 MSPS version. It shares pinout compatibility with the AD9230 series, facilitating drop-in replacements in existing designs. The device is fabricated using BiCMOS technology and is housed in a 56-lead LFCSP package suitable for surface mount applications.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9434 is pin-compatible with the AD9230. Substitution requires minimal design changes but verify SPI configuration registers as control logic may differ between the two families.
