I have soldered directly two OPA2134 op amps is U1 & U2. U3 has OPA2604.
My question is, is this a bad practice in that the last op amp might be colored by the first two? I want to try AD627's and don't want to spend the money populating all three slots with two singles on adapters, too much money. And I don't want to waste the money if I don't get the benefits of that op amp due to the first two being already populated with something else.
any help is greatly appreciated.
