Hello Didier, maybe you are right, and that's not easy to find. I remember an app not from LT (Jim WIlliams?) that discussed how to build a high-accuracy DC output DAC using a Sigma Delta ADC and some logic etc. Finding a 24 bit ADC is pretty easy, ADI, TI, Linear, Maxim etc seem to offer these. One could also build a composite DAC out of two 16 bit DAC's or two 20 bit DAC's etc. The voltage reference is key to good performance here, and should have <<3ppm tempco to get anywhere near the 24 bits of accuracy. bye, Said In a message dated 2/14/2008 02:02:36 Pacific Standard Time, [EMAIL PROTECTED] writes:
What 24 bit DAC do you have in mind? I have been looking for a standalone 24 bit DAC in a small package and have not found anything I liked :-( **************The year's hottest artists on the red carpet at the Grammy Awards.
