Hi all,
I was comparing three IAs (AD624, AD8421, LT1167) which will be used for EMG signal acquisition.
From my comparison (voltage and current noise, CMRR, voltage and current offset, bias current, PSR, nonlinearity etc...) I determined that both the AD8421 and the LT1167 are better than the AD624.
Now I have two questions:
1) Am I correct in saying that the LT1167 is the best from all three ICs?
2) If AD8421 and the LT1167 are better than the AD624, why is AD524 the most expensive from RS components?
