I can understand why the AD9680 would cost less than the AD9680-1 since the -1 has a 1 GSPS bandwidth and the -820 has "only" 820 MSPS bandwidth. But, why is the -820 less expensive than the -500 which only has 500 MSPS of bandwidth?
The pricing for the AD9680-500 appears to be incorrect in the Parametric Search Table. Thanks for bringing this to our attention. Correct AD9680 pricing is reflected in the Ordering Guide section of the AD9680 Product page noted by Umesh above: http://www.analog.com/en/products/analog-to-digital-converters/high-speed-ad-10msps/high-if-ad-converters/ad9680.html#pr…
Our Mkt team is looking into the pricing error in the Parametric search table and will get it corrected shortly.
Thank you for contacting E-Zone regarding the AD9680. The AD9680 is a high input bandwidth device. The analog inputs can sample frequencies up to 2GHz. To facilitate this, we have generated an evaluation board called AD9680-1000EBZ, AD9680-820EBZ, AD9680-500EBZ. These boards use the Marki BAL-0006SMG baluns and hence are expensive.
In order to facilitate the customers who primarily have their IFs in the first Nyquist, we decided to offer a lower bandwidth front end which uses cheaper ETC1-1-13 baluns. These boards we have called AD9680-LF1000EBZ. This is the reason for the price difference.
For example, the AD9680-820EBZ has high input bandwidth front end and is listed at $895 whereas the AD9680-LF820EBZ is listed at $600.
Hope this helps
That is useful information, but I was wondering why the actual A/D converter at 820 MSPS was cheaper than the A/D version rated at 500 MSPS, not the demo board price differences. (Although that is useful information.)
I am not sure where you are getting the pricing information from. I checked on analog.com
the prices seem to scale with speed grade. However the sort/display order seems to be out of whack, with the 500 speed grade slotting in between the 1000 and 820 models.
I will check with our website team to fix the sort order. However I would like to know from you where you are getting the pricing information.
Here is the table:
Sorry, we were checking the product page, not the parametric search table. The pricing is wrong in the parametric search table, and we are having that fixed soon. You can see the correct pricing on the AD9680 product page:
