Is it possible or even worth it to replace 2 single op-amps (like the ad711j) with a dual op-amp (like the lm6172)when i upgrade the op-amps. Is it just a huge headache? Thanks.
(the point being i just happen to have a spare lm6172)
If your pc board is layed out for singles then it would be a pain in the butt to go to a dual. You can still upgrade however with singles, so why not. One thing however, if you're using AD711's keep in mind that other IC's will not have the good DC spect's of the 711, 712's. This is what killed me when I tried to use AD827's in my Classe' CP35 preamp. DC offset was way to high. Good Luck, bobwire
I am assuming that these are compatible as I don't have experience with the adj11j, but in terms of single op-amps, I think that the Burr Brown OPA-627's are magical - magically expensive too ;) - but worth it. Check Digikey - $14 ea.
I was thinking of trying the lcaudio ad825 upgrades (type 4) rather than using that dual op-amp I have, any thoughts? Do you think the burr-brown's are better?
Dan, count yourself lucky - we have to pay closer to £14 ($20) in the UK! Who said DIY was cheap?
My dealers' catalog lists OPA627AP around $12 and OPA627BP $25. I thought they are expensive, was looking for better (European) suppliers...
I'm refering to the OPA627AP. I'm not sure, but doesn't the BP simply have tighter DC specs?
