Hi Claude,The "Minimum Output Current" is kind of misleading. It should be in the "Maximum Output Current" categary. From the data sheet the typical value for it is 60mA, min 50mA.
The 7.5mA supply current per amp is quite large compare with the 2.5mA of the TL074. Just hope the regulators can supply all that require. I think the 7815 and 7915 TO-220 pakage can have a max of 300mA? Maybe heatsink required. I'll just try and see. If they become too hot, I might switch the op-amp. Do you know if both of the amps are used for the DAC or only one of them?
I think it's a direct plug and play for LT1365, 1362, 1359, 1356, etc.
since they are "Unity-Gain Stable"(good tolerance) and there are no other compensation pins needed. I don't have the schematics right now and didn't have time to trace it down. But from what I understand those surrounding resistors should be for gain settings only and should be universal for all similar op-amp.I thought about the AD825, but this needs more rework, it also needs a 6.5mA supply current. I'll take the easier approach first.
Enjoy
