amusing prices

It looks like AD561's would be another thing to keep an eye open for.
The "Low Cost" 10-Bit Monolithic D/A Converter is listed at 38.08 in
Newark's latest price list (for the AD561JN plastic part, you don't
want to know what they want for the "good" ones..)

For comparision, the 12 bit DAC312HP is listed at 7.43. It also looks
like the 312 is the cheapest 12 bit DAC you can buy, but it does have
to have an external current to voltage converter and voltage reference.

I was also comparing the MAX502 that Clay was suggesting that I use
with the DAC80 and it appears that you would actually need to use a
MAX507 unless you wanted to supply your own reference supply.

FWIW, the MAX502 is 11.52 and the MAX507 is 16.24 from Digikey.

For comparision, the ADDAC80N-CBI-V, which is a plasic equivalent
to the Burr-Brown DAC80's is 19.79.

On a completely unrelated note, i've found someone who has the
little PC-mount trim pots that the Atari AVG uses, in all three
values (200,2k,10k) for .70 in 10's.
Circuit Specialists (man, I used to buy stuff from them mail
order when I lived in Milwaukee in the late 70's!)
