Why no announcement? Why no “Modi 3?” Go two paragraphs up. Like I said, it was shades of gray. Although the AK4490 was the current darling of the delta-sigma DAC world at the time it went into Modi 2—being used in products fully 30x the price—it was not head-and-shoulders above the AK4396.
Was it as good as the AK4396? In my opinion, and in Mike’s opinion, yes. Was it better? In my opinion, yes. In Mike’s opinion, it was tradeoffs.
Which meant it was the same product, not a “3.”
...
I mean, in the last week, I’ve done the following:
- Finished up development, including chassis tweaks, thermal and power testing, and A/B measurements for an upcoming product.
- Built three different versions of a current product to see if we could take it to the next level with relatively minor changes. (Thank you, new PCB prototype source that is the magic combination of inexpensive and fast.)
- Worked out a next-level change for that product based on the results of the different versions, then tried drawing it up, and then abandoning it (it wouldn’t fit in the chassis)
- Did extensive testing on another step-up product which may or may not see the light of day.
- Built a new variant on a current product to see if we like it—if we do, it can use the same chassis, which is nice.
- Figured out a third variant on a current product using the same chassis again, and laid it out so we can try that, too. (Again, thank you new PCB source—I no longer have to think about how many protos I want to do.)
- Tested a production change to a current product necessitated by a parts change (yep, again, but this time not Magni).
- Breadboarded a bunch of variations on one of our current topologies, to see their relative performance pluses and minuses.
So Modi 3 coming soon then right
