Hi all,

   

 

   

I was wondering if anyone knew if there was a way to get an 18bit resolution with a sample rate of 10KHz?

   

 

   

I know the delsig adc can do up to 20bits, but the sample rate seems to cap at 3KHz.. which is substantially less than what I need.   

   

I'm guessing the hardware is the limitations, but possibly could by hooking up an external clock could I make it faster?  

   

Is there a different way I should be approaching this other than getting an external chip to do the sampling for me, I'm up for pretty much any idea?

   

 

   

Thanks,

Max @ 18 bits is 3ksps. This value has nothing to do with the clock, it is the ADC limit.
