My opinion is that it has been ignored because of its marginal need.
At $2.75 per 1000 units budgetary price that is not all that far out
of line for low production runs. Now if you want to buy 50 pieces from
your favorite broker who deals in obsolete and hard to find parts, yep
you might pay $10 to $15 per IC. That would be high price. But in a
market that may sell 50K to 100k units per year, you should get the
ICs for about $2.25 a piece. Trust me in a consumer electronics market
50K to 100K units per year is small sales. You start to get into big
sales at around 1 to 5 million units per year. Then you can get big
price breaks.

You need big pots so that the idiots with big screwdrivers can see
them to monkey with.
