How come its so hard to find ADC's with more than 16-20 bits of
resolution
with high conversion rate?(200kSPS+)
Ultimately I would like an ADC and DAC with ~32-bits at 360kSps for use
in
an audio project... although I could deal with the minimum of 24bit at
192khz. I have found a DAC that does the min but no corresponding ADC.
Where should I look for converters like this? and is it possible to get
32-bits? (I've not seen one that does about 24-bits on the major
manufactures sites)
You can't get 32bits, see Phils post for the reason why. But if you
didn't know this already then your wizz-bang audio project might be in
trouble :->
Even if you use superconductors? ;)
BTW, it doesn't take much hardware knowledge to write a digital filter
routine... (I want to make an EQ first... thats very simple and you don't
even have to know anything about anything... most of the stuff needed can be
found online. )
Cirrus Logic make some of the best 24bit ADCs/DACs around:
http://www.cirrus.com/en/products/pro/techs/T1.html
The highest performance 24 bit ADCs and DACs on the market are designed
for geophysical use and only have a bandwidth of a KHz or two.
By high performance, do you mean high quality? 1kSps isn't much and I
wouldn't call that high performance.
Though that site seems to have the best ADC's I've seen(for audio).
Cirrus now includes the very nice converters formerly known as Crystal..
Yes, all the real high end converters are from the Crystal Semi stable,
the ones with the CS prefix.
