Love it! I'm not a big fan of AD opamps. I have the AD8397, AD8620, and AD8599. The ADA4627 (both ARZ and BRZ) are much more refined and dynamic to my ears. Of course, your circuit will determine how it ultimately performs. I'm currently using the ADA4627 as a line out driver for a DAC and as a headphone amp with a pair of BUF634s.

u mean the ADA4627 is outperform the AD8620(ARZ & BRZ)?
how much the voltage u applied on it?
i'm planning to use it on my sound card as LPF + gain stage (voltage applied : +-12V), so i need an excellent opamp to perform this heavy task..
i'm attracted by AD8620 and ADA4627 since they are offer very good spec + sound (AD8620) + SOIC version..
the ADA4627 will be my choice if it is better than AD8620...

You just reminded me, I have to build these today!

I think the ADA4627 is better than AD8620...absolutely. But again, this is based on my ears. The little DAC/AMP that I have these in is 12V.

ok...i think i will go for ADA4627 as long as it is not too bad...
my sound card's output driver stage will allow me to match another opamp with ADA4627 since it is swappable (8DIP)...
thx for ur comments...

I think you will be happy with them. You'll have to post your impressions when you have them installed.

I have about 6-8 units I have to buiuld today so if I get to the building I may not get aorudn to the testing. If I do though I will let you know what I think.

i think this will takes a long time since i nid to find some caps to mod together...
slow and steady...
