Not consumer cards.
But as digital took over, and analog began to die out, there was no reason to do it.
Analog cards are vastly more expensive than digital cards. The technology of analog requires higher and higher spec parts to get to higher frequencies. Those parts are usually not even available, and when they are, they are incredibly expensive, and difficult to implement, because of power, and other constraints. I know, because I've tried to do this myself in my old business. It becomes self defeating.
Digital has the advantage of moving to higher specs whenever the process technology moves down another increment. This allows power requirements to remain about the same. You can't use process size to do that with analog. You need new material technology, and even bigger parts. Those days are over.
It's like my previous industry, that I still involve myself in, which is pro and high end audio.
I have two digital amps that I use for my subwoofers. These are over 1200 watts per channel at 4 ohms. They weigh a bit over 9 pounds per channel. My analog stereo power amp for my ribbons is about 300 watts per channel, and weighs 45 pounds.
In order to do that in analog requires an amp that weighs a good 75 pounds at the minimum, for continuous power, and often more for really good reliability. Because of that they also cost much more.
The efficiency of my amps is about 79%, whereas the efficiency of the analog (solid state) amp would be, at best, 25%, but usually less. Tubes would be about 10%.
That's why we don't see analog cards doing 2560 x 1600 in the consumer space, or even in the pro space anymore, though they used to be used in the medical, weather, and military areas.
