Re: BUF634 problem with midrange grit

24.6.90.239

Per the datasheet BUF634 is primarily intended to be inseted in the feedback loop of an opamp. Your application sounds a little dubious to me. They basic function is to present a very high inpur impedance thus relieving the previous device of current demand and then suppling up to 250mA of current themselves. They don't even need bypass caps I'm not sure what you are using for balanced line drivers. If it's DRV134 they should be able to handle the job alone especially if you have INA134s on the other end.

Suggest you look up the datsaheets for the above. They have somw good application info.
