Guess this begs the question....are you trying to tie into IMPI on the motherboard or having some sort of independent interface?  Often on motherboards, I2C is used to collect analog voltages and temps.  Look around on the MB itself, and you will find a sprinkling of these on them.  We use I2C as a standard on ours.

10Ms/s is enough. I will certainly give Analog
Devices, Maxim, National Semiconductors, Linear
Technology, and Texas Instruments a try. Thank you
for your suggestions.

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
