In the past two or three weeks I have licked the whole internet world
by searching an appropiate SPI AD converter. The AD converters world
is soo huge, I say there isn't an industrial standard for ISA neither
for PCI.

You are probably searching for a parallel output converter, somewhere between
10Ms/s and 35Ms/s (assuming no FIFO is used between the AD and PC card).

Any of these producers will fit with your requirements: Analog Devices
(expensive but high quality), National Semiconductors (nice), Maxim
(huge numbers of AD),
Linear Technology and Texas Instruments (maybe many others).

Maybe you need a differential input AD? Or just a pseudo differential
one. Or a ratiometric input? Sample and hold, succesive
approximations. 8 to 18 bits. 24 bit if sigma-delta conversion. Codec
or audio AD converters. etc.

So, I don't think someone may claim: this is the industrial standard
and no other !

cheers,
Vasile
